-# @BLURB: common ebuild functions for cmake-based packages
-# @DESCRIPTION:
-# The cmake-utils eclass contains functions that make creating ebuilds for
-# cmake-based packages much easier.
-# Its main features are support of out-of-source builds as well as in-source
-# builds and an implementation of the well-known use_enable and use_with
-# functions for CMake.
