16 reavertm 1.52 # 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.

27     # For in-source build it's fixed to ${CMAKE_USE_DIR}.
28     # For out-of-source build it can be overridden, by default it uses
29     # ${WORKDIR}/${P}_build.

43     # If about to be set - needs to be set before invoking cmake-utils_src_configure.
