Hello

I tried that, but it doesn't work in my case.

For my setup, CMAKE_FIND_ROOT_PATH=/usr/i586-pc-mingw32/sys-root/mingw 
but "${CMAKE_C_COMPILER} -print-sysroot" returns 
"/usr/i586-pc-mingw32/sys-root", so the "/mingw" part of the path is 
missing.

What do you get on your setup ?

I have the feeling this doesn't really follow a standard on all linux 
distros, so doing it automatically might be complicated (in my case, I 
don't see how to determine automatically that "/mingw" should be 
appended to "${CMAKE_C_COMPILER} -print-sysroot".
