Beyond Linux® From Scratch - Version 7.9

Chapter 13. Programming

CMake-3.4.3

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-7.9 platform.

CMake Dependencies

Recommended

cURL-7.47.1 and libarchive-3.1.2

Optional

Qt-4.8.7 or Qt-5.5.1 (for the Qt-based GUI), Subversion-1.9.3 (for testing), and Sphinx (for building documents)

Installation of CMake

If Qt4 and Qt5 are installed in /opt, use source setqt4 or source setqt5 to choose which one will be used to build the Qt-based GUI.

Install CMake by running the following commands: 

./bootstrap --prefix=/usr       \
            --system-libs       \
            --mandir=/share/man \
            --no-system-jsoncpp \
            --docdir=/share/doc/cmake-3.4.3 &&
make

To test the results, issue: bin/ctest -j<N> -O cmake-3.4.3-test.log, where <N> is an integer between 1 and the number of system cores. For some systems, it may be necessary to run the tests only for Qt4 using source setq4, then export CXXFLAGS="-std=c++11" before the ./bootstrap ...) command. If used, be sure to unset CXXFLAGS after the tests. One of the problematic tests relates to the test procedures finding the correct Qt files. Eight of 447 tests are known to fail under some circumstances related to Gtk+2 and c++ standards.

Now, as the root user: 

make install

Command Explanations

--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.
