# === Package-settable variables ===
#
# CMAKE_DEPENDENCIES_REWRITE
#	A list of files (XXX: variable name) relative to WRKSRC in
#	which, after configuring the package, buildlink3 dependencies
#	are resolved to the real ones.
#
# CMAKE_MODULE_PATH_OVERRIDE
#	A list of files relative to WRKSRC in which the CMAKE_MODULE_PATH
#	variable is adjusted to include the path from the pkgsrc wrappers.
#	The file ${WRKSRC}/CMakeLists.txt is always appended to this list.
