The dirs provided with -L are only needed when using find_library() to  
put libraries with full path into wxWidgets_LIBRARIES. After that, it  
should not be needed anymore.

So such a module only needs to return: xxx_LIBRARIES_<> with full-path  
libraries and (optional) support for (general|debug|optimized),  
xxx_INCLUDE_DIRS for position of header files, xxx_COMPILE_FLAGS_<>  
and xxx_LINK_FLAGS_<> (with support for <> being at least RELEASE and  
DEBUG).
Problem may be that the last two are highly compiler-specific :-(

Anything less than that is incomplete, IMHO.
