Well, it is not so much a bug as it is an unsupported use case. I have
only added select options for boolean paramenters (i.e., debug,
unicode, universal, static). I will try to figure out a clean way to
add support for this.

Could you submit this to the cmake bug tracker:

Please add the exact wx-config command line that gives you the correct
results for you.
