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 12.1 platform.

Installation of Extra Cmake Modules

Install Extra Cmake Modules by running the following commands:

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

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

mkdir build &&
cd    build &&

cmake -DCMAKE_INSTALL_PREFIX=/usr .. &&

This package does not come with a test suite.



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.
