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