# http://public.kitware.com/pipermail/cmake/2006-July/010334.html.
# See also, CMakeCInformation.cmake.  There are also C++, and Fortran-specific
# overrides that can be done.  However, I prefer putting overrides in just
# one file so I use the overall variable CMAKE_USER_MAKE_RULES_OVERRIDE

# be processed by cmake in a specific order e.g., due to get_target_property
# invocations.  Note, this order has nothing to do with the order which make
# processes these subdirectories at build time.  That build-time order
# is determined by the dependencies between targets and also by file
# dependencies that are established by the cmake configuration files.
