This is not passed as --sysroot. However, cmake master supports a 
CMAKE_SYSROOT variable.

 http://www.cmake.org/cmake/help/git-master/variable/CMAKE_SYSROOT.html

Please test a master build or a nightly build so that we know CMAKE_SYSROOT 
works for you.
 
 SET(CMAKE_SYSROOT
 /home/bogdan/dev/src/tizenbuildtools/emulator/GBS-ROOT/local/BUILD-
ROOTS/scratch.i586.0)


Thanks,

Steve.
