[CMake] Forwarding parameters to cmake through cmake-gui

[J Decker]

sorry and I should ask; after reading a bit more context;

why are you using cmake-gui if you have -D's to pass already?

but the macro does allow you to export them to the environment
instead; it doesn't update what was configured though; and actually
most places I use the same macro but without the CACHE STRING option
on the SET().
