# @BLURB: Support eclass for packages that use KDE Frameworks with ECM.
# @DESCRIPTION:
# This eclass is intended to streamline the creation of ebuilds for packages
# that use cmake and KDE Frameworks' extra-cmake-modules, thereby following
# some of their packaging conventions. It is primarily intended for the three
# upstream release groups (Frameworks, Plasma, Gear) but also for any
# other package that follows similar conventions.
#
# This eclass unconditionally inherits cmake.eclass and all its public
# variables and helper functions (not phase functions) may be considered as part
# of this eclass's API.
#
# This eclass's phase functions are not intended to be mixed and matched, so if
# any phase functions are overridden the version here should also be called.
