Use CMake find_dependency in CMake config file instead of find_package
Summary:
find_dependency is preferred in config files to correctly propagate the QUIET and REQUIRED parameters from the enclosing find_package call. See https://cmake.org/cmake/help/v3.0/module/CMakeFindDependencyMacro.html#module:CMakeFindDependencyMacro.
The macro does not support COMPONENTS before CMake 3.8 so I split the original find_package up into two find_dependency calls. I also removed the NO_MODULE parameter. This is consistent with how the rest of KDE uses find_dependency.
