CMake-3.21.2

Introduction to CMake

The CMake package contains a modern toolset used for generating Makefiles. It is a successor of the auto-generated configure script and aims to be platform- and compiler-independent. A significant user of CMake is KDE since version 4.

This package is known to build and work properly using an LFS-11.0 platform.

Installation of CMake

Install CMake by running the following commands:

sed -i '/"lib64"/s/64//' Modules/GNUInstallDirs.cmake &&

./bootstrap --prefix=/usr        \
            --system-libs        \
            --mandir=/share/man  \
            --no-system-jsoncpp  \
            --no-system-librhash \
            --docdir=/share/doc/cmake-3.21.2 &&
make

To test the results, issue: LC_ALL=en_US.UTF-8 bin/ctest -j<N> -O cmake-3.21.2-test.log, where <N> is an integer between 1 and the number of system cores. Setting LC_ALL is needed to prevent some test failures when some of the locale variables are set to non English locales. One test, RunCMake.CMP0125. is known to fail.

If you want to investigate a problem with a given "problem1-test", use bin/ctest -R "problem1-test" and, to omit it, use bin/ctest -E "problem1-test". These options can be used together: bin/ctest -R "problem1-test" -E "problem2-test". Option -N can be used to display all available tests, and you can run bin/ctest for a sub-set of tests by using separated by spaces names or numbers as options. Option -/-help can be used to show all options.

Now, as the root user:

make install

Command Explanations

sed ... Modules/GNUInstallDirs.cmake: This command disables applications using cmake from attempting to install files in /usr/lib64/.

--system-libs: This switch forces the build system to link against Zlib, Bzip2, cURL, nghttp2, Expat and libarchive installed on the system.

--no-system-jsoncpp: This switch removes the JSON-C++ library from the list of system libraries. A bundled version of that library is used instead.

--no-system-librhash: This switch removes the librhash library from the list of system libraries used. A bundled version of that library is used instead.

--qt-gui: This switch enables building the Qt-based GUI for CMake.

--parallel=: This switch enables performing the CMake bootstrap with multiple jobs at one time.
