Weird...

The "cmake_parse_arguments" macro calls the "_cmake_parse_arguments"
function , but instead the "cmake_parse_arguments" macro (without the
underscore) is called again, and that causes the infinite loop.
Renaming "_cmake_parse_arguments" to "_cmake_parse_arguments_real" fixes
it...

Even weirder, it happens only for kde frameworks, I couldn't reproduce
anywhere else, and all the unit tests pass:

Do you have any idea why this happens? I can just rename the function in
order to fix it, but this looks like a bug in cmake, not in the module.
