# - MACRO_OPTIONAL_FIND_PACKAGE() combines FIND_PACKAGE() with an OPTION()
# MACRO_OPTIONAL_FIND_PACKAGE( <name> [QUIT] )
# This macro is a combination of OPTION() and FIND_PACKAGE(), it
# works like FIND_PACKAGE(), but additionally it automatically creates
# an option name WITH_<name>, which can be disabled via the cmake GUI.
# or via -DWITH_<name>=OFF
# The standard <name>_FOUND variables can be used in the same way
# as when using the normal FIND_PACKAGE()
