CMake

Introduction

CMake is a cross-platform, open-source build system generator.For full documentation visit the CMake Home Page and theCMake Documentation Page. The CMake Community Wiki alsoreferences useful guides and recipes.

CMake is maintained and supported by Kitware and developed incollaboration with a productive community of contributors.

Building CMake

Supported Platforms

• Microsoft Windows
• Apple macOS
• Linux
• FreeBSD
• OpenBSD
• Solaris
• AIX

Other UNIX-like operating systems may work too out of the box, if notit should not be a major problem to port CMake to this platform.Please post to the CMake Discourse Forum to ask if others havehad experience with the platform.

Building CMake from Scratch

UNIX/Mac OSX/MinGW/MSYS/Cygwin

You need to have a C++ compiler (supporting C++11) 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 custominstallation directory for CMake. Once this has finished successfully,run make and make install.

For example, if you simply want to build and install CMake from source,you can build directly in the source tree:

$ ./bootstrap && make && sudo make install

Or, if you plan to develop CMake or otherwise run the test suite, createa separate build tree:

$ mkdir cmake-build && cd cmake-build$ ../cmake-source/bootstrap && make

Windows

There are two ways for building CMake under Windows:

1. Compile with MSVC from VS 2015 or later.You need to download and install a binary release of CMake. You can getthese releases from the CMake Download Page. Then proceed with theinstructions below for Building CMake with CMake.

2. Bootstrap with MinGW under MSYS2.Download and install MSYS2. Then install the required build tools:

   $ pacman -S --needed git base-devel mingw-w64-x86_64-gcc

   and bootstrap as above.

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 preferredoptions and generators. Then build it and install it.For instructions how to do this, see documentation on Running CMake.

To build the documentation, install Sphinx and configure CMake with-DSPHINX_HTML=ON and/or -DSPHINX_MAN=ON to enable the "html" or"man" builder. Add -DSPHINX_EXECUTABLE=/path/to/sphinx-build if thetool is not found automatically.

Reporting Bugs

If you have found a bug:

1. If you have a patch, please read the CONTRIBUTING.rst document.
2. Otherwise, please post to the CMake Discourse Forum and ask aboutthe expected and observed behaviors to determine if it is reallya bug.
3. Finally, if the issue is not resolved by the above steps, openan entry in the CMake Issue Tracker.
