+# @BLURB: common ebuild functions for cmake-based packages
+# @DESCRIPTION:
+# The cmake-utils eclass is base.eclass(5) wrapper that makes creating ebuilds for
+# cmake-based packages much easier.
+# It provides all inherited features (DOCS, HTML_DOCS, PATCHES) along with out-of-source
+# builds (default), in-source builds and an implementation of the well-known use_enable
+# and use_with functions for CMake.
+
+# @ECLASS-VARIABLE: WANT_CMAKE
+# @DESCRIPTION:
+# Specify if cmake-utils eclass should depend on cmake optionaly or not.
+# This is usefull when only part of aplication is using cmake build system.
+# Valid values are: always [default], optional (where the value is the useflag
+# used for optionality)
+WANT_CMAKE="${WANT_CMAKE:-always}"
+
+# @ECLASS-VARIABLE: CMAKE_MIN_VERSION
+# @DESCRIPTION:
+# Specify the minimum required CMake version.  Default is 2.8.4
+CMAKE_MIN_VERSION="${CMAKE_MIN_VERSION:-2.8.4}"
+
+# @ECLASS-VARIABLE: CMAKE_REMOVE_MODULES_LIST

+# in order to force packages to use the system version.
