The Extra CMake Modules package, or ECM, adds to the modules provided by CMake, including ones used by
find_package() to find common software, ones that can be used directly in
CMakeLists.txt files to perform common tasks and toolchain files that must be specified on the commandline by the user.
In addition, it provides common build settings used in software produced by the KDE community.
While the driving force of this module is to reduce duplication in CMake scripts across KDE software, it is intended to be useful for any software that uses the CMake build system.
