I found out now that the bootstrap thingy is a shell script ... stupid me.
So I found that I can set the CXXFLAGS and CFLAGS env vars beforehand.

... still with a 64bit cmake exe, it finds only the 32bit libX11 - even when I
set explicitely FIND_LIBRARY_USE_LIB64_PATHS to TRUE.

How can I tell cmake to find the 64bit X11 libs ?
