you need to do :

EXECUTE_PROCESS(
   COMMAND ${CMAKE_C_COMPILER} -print-sysroot
   OUTPUT_VARIABLE CMAKE_FIND_ROOT_PATH
   OUTPUT_STRIP_TRAILING_WHITESPACE
)

But it doesn't solve the "/mingw" part to add or not to the path.

I added this to the current sources tree, at least for people using 
"/mingw" it will remove the need to edit cmake/Toolchain-mingw32.cmake 
to change "/usr/i586-pc-mingw32/sys-root"
