### Extra Cmake Modules Dependencies

#### Required

CMake-3.30.2

#### Optional

sphinx-8.0.2 (for building documentation), PyQt (experimental support for building KDE Python bindings), and ReuseTool (for running internal tests)

## 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 -D CMAKE_INSTALL_PREFIX=/usr .. &&
    make

This package does not come with a test suite.

### Note

Unlike other KF6 packages, this module is installed in /usr because it can be used by some non-KF6 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.

## Contents

Installed Programs: None
Installed Libraries: None
Installed Directories: /usr/share/ECM and /usr/share/doc/ECM (if documentation was built)
