Building CMake

Supported Platforms

MS Windows, Mac OS X, Linux, FreeBSD, Solaris, HP-UX, IRIX, BeOS, QNX

Other UNIX-like operating systems may work too out of the box, if not it should not be a major problem to port CMake to this platform. Subscribe and post to the CMake Users List to ask if others have had experience with the platform.

Building CMake from Scratch


You need to have a compiler and a make installed. Run the bootstrap script you find in the source directory of CMake. You can use the --help option to see the supported options. You may use the --prefix=<install_prefix> option to specify a custom installation directory for CMake. You can run the bootstrap script from within the CMake source directory or any other build directory of your choice. Once this has finished successfully, run make and make install. In summary:

$ ./bootstrap && make && make install


You need to download and install a binary release of CMake in order to build CMake. You can get these releases from the CMake Download Page . Then proceed with the instructions below.

Building CMake with CMake

You can build CMake as any other project with a CMake-based build system: run the installed CMake on the sources of this CMake with your preferred options and generators. Then build it and install it. For instructions how to do this, see documentation on Running CMake.

Reporting Bugs

If you have found a bug:

  1. If you have a patch, please read the CONTRIBUTING.rst document.
  2. Otherwise, please join the CMake Users List and ask about the expected and observed behaviors to determine if it is really a bug.
  3. Finally, if the issue is not resolved by the above steps, open an entry in the CMake Issue Tracker.


See CONTRIBUTING.rst for instructions to contribute.
