Chapter 13. Programming

CMake-3.15.2

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-9.0 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-3.15.2 &&
make

To test the results, issue: bin/ctest -j<N> -O cmake-3.15.2-test.log, where <N> is an integer between 1 and the number of system cores. In case the environment variable LANG is set to a non-blank value and failures occur, try running the tests without having LANG set. One test, RunCMake.CommandLineTar, is known to fail.

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, 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.

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