# As of CMake 2.8.3, Fink and MacPorts search paths are appended to the
# default search prefix paths, but the nicer thing would be if they are
# prepended to the default, so that is fixed here.

# Prepend the default search path locations, in case for some reason the
# ports/brew/fink executables are not found.
# If they are found, the actual paths will be pre-pended again below.
