13 # @BLURB: common ebuild functions for cmake-based packages
14 # @DESCRIPTION:
15 # The cmake-utils eclass makes creating ebuilds for cmake-based packages much easier.
16 # It provides all inherited features (DOCS, HTML_DOCS, PATCHES) along with out-of-source
17 # builds (default), in-source builds and an implementation of the well-known use_enable
18 # and use_with functions for CMake.
