RFR(M): 8057538: Build the freetype library during configure on Windows

Hello Volker,


It seems to me like the warning about freetype src only working on 
windows will always be printed on other platforms? The conditions need 
to be moved to separate if statements.

I can see the point adding the code, even if commented out, as 
documentation for how it could be solved. I think the comment around 
msbuild detection is probably enough though.
