Just to clarify, you can point CMake at either the source directory from the build directory, or at an existing build directory from anywhere. Note that working from the build directory is historically much more common, and some tools and commands (including CTest <3.20) still require running from the build directory. You should try to get used to using -build, as that will free you from using only make to build. So which set of methods should you use? As long as you do not forget to type the build directory as the argument, staying out of the build directory is shorter, and making source changes is easier from the source directory. # CMake 3.15+ only # From the source directory (pick one) ~/package $ make -C build install ~/package $ cmake -build build -target install ~/package $ cmake -install build # CMake 3.15+ only target install ~/package/build $ cmake -install. # From the build directory (pick one) ~/package/build $ make install ~/package/build $ cmake -build. If you are using a newer version of CMake (which you usually should be, except for checking compatibility with older CMake), you can instead do this: if you'd like, and it will call make or whatever build tool you are using. You can replace the make line with cmake -build. ~/package $ mkdir build ~/package $ cd build ~/package/build $ cmake. Here's the Classic CMake Build Procedure (TM): You can technically do an in-source build, but you'll have to be careful not to overwrite files or add them to git, so just don't. Unless otherwise noted, you should always make a build directory and build from there. This is true for almost all CMake projects, which is almost everything. In order to build the Windows version of CMake, you will need a current binary installation of CMake to bootstrap the build process.Before writing CMake, let's make sure you know how to run it to make things. On UNIX, one may use the bootstrap script provided in the source tree to build CMake. Development is managed on Kitware’s GitLab instance: Nightly BinariesĪlternatively one may build from source. It is being produced so that users can test bug fixes done upstream without having to build CMake. Other than passing all of the tests in CMake, this version of CMake should not be expected to work in a production environment. Source distributions: PlatformĮach night binaries are created as part of the testing process. To build the source distributions, unpack them with zip or tar and follow the instructions in README.rst at the top of the source tree. This prefix can be removed as long as the share, bin, man and doc directories are moved relative to each other. For example, the linux-x86_64 tar file is all under the directory cmake–linux-x86_64. They are prefixed by the version of CMake. The tar file distributions can be untared in any directory. The files are compressed tar files of the install tree. The files are gziped tar files of the install tree. sh file, run it with /bin/sh and follow the directions. sh files are self extracting gziped tar files. The release was packaged with CPack which is included as part of the release. Source distributions: PlatformĬmake-3.28.Ĭmake-3.28.
