+#
+# Provide support for CMake based projects
+#
+# Feature:		cmake
+# Usage:		USES=cmake or USES=cmake:ARGS
+# Valid ARGS:		insource, run, noninja
+# ARGS description:
+# insource		do not perform an out-of-source build
+# noninja		don't use ninja instead of make
+#			Setting this should be an exception, and hints to an issue
+#			inside the ports build system.
+#			A few corner cases never use ninja, and are handled, to reduce
+#			the usage of 'noninja'.:
+#				1) fortran ports
+#				2) ports that set BUILD_- or INSTALL_WRKSRC to
+#				   something different than CONFIGURE_WRKSRC
+# run			add a runtime dependency on cmake
+#
+#
+# Additional variables that affect cmake behaviour:
+#
+# User defined variables:
+# CMAKE_NOCOLOR		- Disable colour build output
+#			Default: not set, unless BATCH or PACKAGE_BUILDING is defined
+#
+# Variables for ports:
+# CMAKE_ON		Appends -D<var>:bool=ON  to the CMAKE_ARGS,
+# CMAKE_OFF		Appends -D<var>:bool=OFF to the CMAKE_ARGS.
+# CMAKE_ARGS		- Arguments passed to cmake
+#			Default: see below
+# CMAKE_BUILD_TYPE	- Type of build (cmake predefined build types).
+#			Projects may have their own build profiles.
+#			CMake supports the following types: Debug,
+#			Release, RelWithDebInfo and MinSizeRel.
+#			Debug and Release profiles respect system
+#			CFLAGS, RelWithDebInfo and MinSizeRel will set
+#			CFLAGS to "-O2 -g" and "-Os -DNDEBUG".
+#			Default: Release, if WITH_DEBUG is not set,
+#			Debug otherwise
+# CMAKE_SOURCE_PATH	- Path to the source directory
+#			Default: ${WRKSRC}
