[CMake] problem with ADD_DEFINITION

I recently submitted a better (but incompatible) version of a PKGCONFIG
macro, which already fills the relevant variables and thus is far
simpler to use. I did not get any response or the requested discussion
:-/ Seeing you still proposing the old macro makes things even more sad :-/

Btw., after working even more with cmake I see even improvement for my
version of the macro. Instead of passing all variables to the macro you
just pass a name prefix and make the macro define the variables
following the naming schema of similar macros itself - similar to the
way the equivalent autoconf macro works.
