My suggested solution would be to use something like

add_definitions(${KDE4_USE_DEFAULT_VISIBILITY})

which would expand on those platforms where we support both hidden and default 
visibility to something like -fvisibility=default.

we have something similar for enabling C++ exception support when needed. 

Good enough?
