Find VC Express during default generator selection (#12917) 

CMake doesn't find Visual C++ Express and uses "NMake Makefiles"
generator by default when one calls cmake WITHOUT using the -G options.
Teach CMake to find VC Express to use it as the default generator just
like the commercial versions.
