Introduction to Extra Cmake Modules

The Extra Cmake Modules package contains extra CMake modules used by KDE Frameworks 5 and other packages.

This package is known to build and work properly using an LFS 12.0 platform.

Package Information

Extra Cmake Modules Dependencies

Required

CMake-3.27.2

Optional

sphinx-7.1.2 (for building documentation) and PyQt (experimental support for building KDE Python bindings)

Installation of Extra Cmake Modules

Install Extra Cmake Modules by running the following commands: 

sed -i '/"lib64"/s/64//' kde-modules/KDEInstallDirsCommon.cmake &&

sed -e '/PACKAGE_INIT/i set(SAVE_PACKAGE_PREFIX_DIR "${PACKAGE_PREFIX_DIR}")' \
    -e '/^include/a set(PACKAGE_PREFIX_DIR "${SAVE_PACKAGE_PREFIX_DIR}")' \
    -i ECMConfig.cmake.in &&

mkdir build &&
cd    build &&

cmake -DCMAKE_INSTALL_PREFIX=/usr .. &&
make

This package does not come with a test suite.

[Note]

Note

Unlike other KF5 packages, this module is installed in /usr because it can be used by some non-KF5 packages.

Now, as the root user: 

make install

Command Explanations

sed ... Modules/KDEInstallDirs.cmake: This command disables applications using cmake from attempting to install files in a lib64 sub-directory.

sed ... ECMConfig.cmake.in: This command protects the global cmake variable PACKAGE_PREFIX_DIR from being changed when checking ECM presence: since we install ECM into /usr, the check would set that variable to /usr, while most KDE packages expect it to be set to /opt/kf5 and would fail to build if it is set to something else.
