Description
This my 1st time trying to compile a project.
I’m following building instructions of MSYS2 Method Building-on-Windows
but I’m facing this error.
Cmake command is not found
$ cmake .. -G 'Unix Makefiles' -DUSE_SDL2_LIBS=1
bash: cmake: command not found
make should have been downloaded & installed as part of:pacman --noconfirm --needed -Sy pkg-config make mingw-w64-i686-toolchain mingw-w64-i686-cmake mingw-w64-i686-zlib mingw-w64-i686-SDL2 mingw-w64-i686-SDL2_image mingw-w64-i686-SDL2_mixer
I’m using Windows 10×64-bit.
This post helps you to fix the “cmake: command not found” error encountered during the build process of your software. There are two major reasons for getting cmake command errors, either cmake is not installed or Path is not correctly set up. It doesn’t matter, which operating system you have. Following this post step by step will get this issue resolved for sure.
Below mentioned are the types of errors that occur while working with the “cmake” command –
- cmake: command not found
- cmake command not found macOS
- autogen.sh cmake command not found
- /bin/sh cmake command not found
- ‘cmake’ is not recognized as an internal or external command, operable program or batch file
- command ‘cmake’ not found
- bash: /snap/bin/cmake: No such file or directory
Why am I getting the “cmake: command not found” error?
Following are the reason for getting the cmake command not found issue –
- cmake is not installed in your operating system
- cmake is installed but PATH or environmental variable is not setup correctly
Let’s assume you are trying to build software which is trying to run “build && cmake” commands and you are getting cmake errors. It means you don’t have the CMake package installed in your macOS.
To solve this CMake issue, we will follow 3 steps approach –
- Check if CMake is installed or not
- If it’s not installed, install the cmake using the right way.
- If CMake is installed but not working, then look for the PATH variable.
The above-mentioned approach is applicable to all operating systems whether it’s Windows, Debian, RedHat or macOS.
How to check “CMake” package is installed or not
The best way is to run the CMake command –
- Open a terminal in macOS
- Run
cmakecommand see the output
$ cmake
If it shows the cmake help, then cmake is installed in your system and your life is sorted, else you need to install cmake using the following command.
$ brew install cmake- Alternatively, you can also go to the cmake download page and download the precompiled binaries as disk image “.dmg” or “.tar.gz” (tarball) binary as per your macOS version.
- Copy CMake.app into /Applications (or a custom location) and then double click to run it. Then follow the “How to Install For Command Line Use” menu item
Once you install the cmake it will automatically be available in the PATH. but in case you don’t have that automatically and get the cmake: command not found error, then you need to set up the cmake PATH manually using the following commands –
How to setup PATH for cmake in macOS
- Open
.bash_profileor.bashrcin your home directory using vim or nano editor. - Add the following line to the end of the file and save the file.
export PATH=”/Applications/CMake.app/Contents/bin”:”$PATH”
- If you want to create symlinks to ‘/usr/local/bin’, run the following command from the terminal
$ sudo "/Applications/CMake.app/Contents/bin/cmake-gui" --install
How to fix command ‘cmake’ not found error in Linux
If you use Ubuntu or any other Debian-based Linux and get “cmake: command not found errors“, then follow these series of commands –
Step-1 check for existing cmake installation
As shown in the above image, cmake is not installed in my Linux system.
Step2- Install cmake, if not installed already
How to install cmake in Linux – 4 Methods
There are 4 ways to install cmake in your Debian Linux system like Ubuntu, LinuxMint, Kubuntu, Kali Linux etc.
- 1. Using the apt command
Run the following commands –
$ sudo apt update $ sudo apt install cmake
- 2. Using the snap command as the apt command is going to obsolete soon
$ sudo snap install cmake --classic
- By using pre-compiled binaries available on the make download page.
- 3. Download the cmake-3.24.2-linux-x86_64.sh file and execute it.
$ bash cmake-3.24.2-linux-x86_64.sh
- Accept license by typing “y” and either accept the default location to install or provide your custom directory.
** Note – whatever the directory location you will provide in the above step, the same path you need to include in $PATH manually if the cmake command gives you an error.
For example, in my case, I will add the following line to the last of .bashrc or .bash_profile file in the user’s home directory
$ export PATH=$PATH:/home/dev/Downloads/cmake-3.24.2-linux-x86_64/bin
- Check the command
"cmake"is running successfully
$ cmake
How to fix ‘cmake’ is not recognized as an internal or external command, operable program or batch file error in Windows
In the case of the Windows operating system, if you get cmake command errors, then follow the below-mentioned process to fix it.
- Download cmake binaries from the cmake website
- Double-click on the installer and click “
next” on the welcome page - Accept the license and hit
nextin the wizard
- Important step – Select the option to add the CMake directory to the system PATH.
You will get 3 options –
- Do not add CMake to the system PATH – If you have selected this option, then you need to add the CMake path manually in the system after installation. That is one of the reasons when you have cmake installed and still, you get “‘cmake’ is not recognized as an internal or external command” error. So don’t select this option.
- Add CMake to the system PATH for all users – If you log in with different users to your system, then you can select this option. It will set up the cmake PATH variable for all users, who is present on the system.
- Add CMake to the system PATH for the current user – If you are the only user, then this is the recommended option.
You can select either option 2 or 3 based on your requirement, both will set up the PATH variable in your environment and will fix the cmake command errors.
- Select custom or leave it to default for the cmake installation directory.
- Then Click
Installand accept select “Yes” in case of user control dialogue box permission
- Click Finish, once the cmake installation is done
- Open the command prompt and run the
cmakecommand to validate.
c:\> cmake
How to install CMake in Docker
Add this line to install CMake in the Docker file –
#!/bin/bash wget -qO- "https://github.com/Kitware/CMake/releases/download/v3.24.2/cmake-3.24.2-linux-x86_64.tar.gz" | tar --strip-components=1 -xz -C /usr/local
Change the version with your required version, I have shown an example of v3.24.2 latest available while writing this article. If you get the error wget command not found, then add appt update && apt install wget in your file.
End note
The fundamental approach is the same to troubleshoot the CMake command not found error in all operating systems –
- Check for cmake installation
- Install cmake as shown in this post for your operating systems
- setup PATH or Environment variable, if required
- Run cmake and build apps
Leave your feedback or comments, if you face any other issues in the cmake command.

1 Answer. cmake -G «MinGW Makefiles» is effectively the right command to
inform CMake you want to use MinGW. To be complete, you should create a
separate folder, let’s call it build, and call cmake from it to make an out-
of-source build: The problem here is gitql doesn’t provide any CMakeLists.txt
file in the repository, so you just can’t use
-- Building for: NMake Makefiles
-- The C compiler identification is unknown
CMake Error at CMakeLists.txt:14 (PROJECT):
The CMAKE_C_COMPILER:
cl
is not a full path and was not found in the PATH.
To use the NMake generator with Visual C++, cmake must be run from a shell
that can use the compiler cl from the command line. This environment is
unable to invoke the cl compiler. To fix this problem, run cmake from the
Visual Studio Command Prompt (vcvarsall.bat).
Tell CMake where to find the compiler by setting either the environment
variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
the compiler, or to the compiler name if it is in the PATH.

What Are the Causes of the Cmake Command Not Found Error?
The CMake command not found Debian error is caused by including the missing CMake tool on your machine. Another problem can be the CMake directory path not assigned to the PATH environment variable. So, in case of any of the given situations, you’ll receive the stated error.
– You Forgot To Install CMAKE
Installing CMAKE is essential for running the CMAKE commands efficiently. Thus, it might be possible that you have forgotten to install CMAKE, giving a chance to the same error to pop up on your screen. This cause is valid for a variety of operating systems available. So, whichever operating system you are using currently, the absence of CMAKE will give you the same error irrespective of your OS.
– You Haven’t Set the PATH Environment Variable To the CMAKE Path
Not setting the PATH environment variable to your CMAKE directory can result in the given error. Although initializing the given variable with the CMAKE path is usually included in the CMAKE installation steps, it is possible that you have missed it, making the said error appear on your system.
Note that this problem relates to the above error when it occurs on Windows or macOS operating systems. Thus, if you are a Windows or mac user, you might find it relevant.
What Are the Best Solutions to Cmake Command Not Found Error?
The best solutions for the CMake: command not found CentOS error include installing CMake on your PC and ensuring that the path of the CMake directory is assigned to the PATH environment variable in Windows and mac.
Remember that the way to install CMake may vary among different systems.
– Install CMAKE on Windows
You should install CMAKE on Windows to get rid of the CMAKE command not found Windows error. You’ll need to begin by visiting the download page of the CMAKE official website, downloading the precompiled binary or the source code distribution for Windows, and installing the same.
If you choose to download the binary distribution, you’ll see that it’s available as an MSI package and a ZIP file. Opting for the MSI package will give you the option to update the PATH variable with the CMAKE directory path. However, if you don’t use that option, you’ll need to execute the set command to manually set the given variable to the directory path that might look like C:\ProgramFiles\CMake\bin.
Remember that if you would like to go with building CMAKE from the source distribution, then downloading the source release won’t be enough. You’ll need to install the latest binary version of CMAKE to proceed with the building process. After installing the binary version, you’ll have to select CMAKE as the source directory before choosing a binary directory for the resulting executables to make things work.
– CMAKE Installation on Linux or Unix
As the missing CMAKE is the cause, it would be best to install CMAKE on your Linux or Unix system to remove the error permanently. Similar to the Windows case, you can download the precompiled binary ZIP file/MSI package or a source release from the CMAKE official website.
Next, you’ll only need to install the downloaded ZIP file/MSI package on your computer to have CMAKE and kick away the error.
However, for the source release criterion, you’ll need to run the following commands paired with a bootstrap script to complete the installation.
make
make install
Furthermore, if you are using a compiler other than the GNU C++ compiler, you’ll have to inform it to the bootstrap script by setting the CC and CXX environment variables before running it. Preceding the bootstrap script execution with env CC=cc CXX=CC will tell which compiler you want to use. In such a situation, the script execution will look like env CC=cc CXX=CC ./bootstrap. Here are a few more points that you should always keep in mind:
- Running the make install command is optional.
- CMake will execute from the build directory.
- Boostrap will build CMake without any optimization or debug flags by default.
- You can enable the optimizations by tweaking the ./bootstrap script like ./bootstrap — -DCMAKE_BUILD_TYPE:STRING=Release.
Besides this, you can run sudo apt-get update && sudo apt-get upgrade, and sudo apt-get install cmake to fix the CMake command not found CentOS 7 and CMake command not found Raspberry Pi errors instantly.
– Say Yes To CMAKE on macOS
To resolve the CMake command not found mac error, you’ll have to welcome CMake on your macOS system. The CMake official website’s download page offers precompiled binaries and source distributions for the mac platform as well. So, you can download the file and install it to get things working.
Know that the binary files for macOS are available as tarballs and disk images. You can freely choose your preferred format. Moreover, after downloading and installing the precompiled binary, you’ll need to copy the CMake.app to your desired location, such as /Applications, and execute it. Next, if you talk about setting the PATH environment variable, you’ll either need to follow the instructions provided in the How to Install For Command Line Use menu item or go for manual variable setting process.
Please note that downloading and building CMake from the source release will require you to follow the same steps specified in the CMake installation on the Linux section.
– Let the build-essential or Homebrew Package Do the Work
The build-essential is commonly known as a meta-package, and Homebrew is a popular package manager. Thus, you can use any one of them to install CMake and, eventually, make the CMake command not found Ubuntu error go away without taking much of your time.
The command using the build-essential package has been attached here: sudo apt-get install build-essential cmake. However, to take help from the Homebrew package, you’ll need to run the brew install cmake command. Once you execute any one of the given commands, you won’t face the same error again while running the CMake commands.
FAQs
1. How To Confirm If CMake Is Installed Successfully on Your PC?
You can confirm if CMake is installed successfully on your PC by running the cmake command followed by the –version or -version option like cmake –version. If CMake is installed, you’ll get its version number in the output. If it’s not, you’ll see the above error again.
2. What Is the Purpose of the cmake install Command?
The purpose of the CMake install command is to specify the way a project should be installed. A project executes the said command in the CMakeLists file to inform CMake about the way the installation scripts can be generated. Next, the same scripts will be executed at the installation time.
3. What Are Some Great Alternatives to CMake?
Some great alternatives to CMake are GNU Make, GNU Automake, Leiningen, SCons, FinalBuilder, A-A-P, Apache Buildr, and Distcc. Furthermore, you can check out the features and functionalities offered by each software to see which one among these fits the best to your requirements.
Conclusion
After reading this post, it’s clear that the CMake command not found Linux error is nothing but a signal that will light up when you execute the CMake commands without ensuring that your machine has the CMake tool and the PATH is set to the CMake directory path. So, having the tool is the key and the one and only fixing technique for the same error. Here you go with some noteworthy points for a quick recap of the above guide.
- You can download the CMake precompiled binary based on your operating system from the CMake official website.
- You can download and build CMake from the source releases available on the CMake official website.
- It would be safe to use a package manager, such as Homebrew or build-essential, to install CMake.
- The advanced package tool (APT) can make it easier for you to install CMake on Linux systems.
It won’t be wrong to say that there are a bunch of ways to let CMake enter your PC and make it possible for the CMake commands to run flawlessly.

В данной статье будут даны рекомендации о том, что делать в случаях, когда при попытке собрать что-либо из исходников, вы получаете ошибку, говорящую о том, что cmake не найден в вашей системе.
Описание
Эту ошибку очень часто можно встретить при начале компиляции чего-либо из исходного кода в дистрибутивах, которые имеют в своем названии minimal. Например, Ubuntu-1610-yakkety-64-minimal 
cmake: command not found
Она означает, что в вашей системе не найдена кроссплатформенная система автоматизации сборки программного обеспечения из исходного кода (она же и есть cmake). Для установки cmake в большинстве современных дистрибутивов достаточно сделать следующее:
sudo apt-get update
sudo apt-get install cmakeПосле этого можно пробовать запустить cmake еще раз.
