[Cmake] Build Type.

[Nitin Gupta]

Hi,
	I'm wondering is there a way to set the type
	of configurations to be generated for VC++
	projects. By default it generates 4 configurations
	"Debug Release RelWithDebInfo MinSizeRel". 
	I tried setting CMAKE_BUILD_TYPE from CMakeSetup
	and from  CMakeLists.txt file itself (as CACHE
	FORCE entry). CMake would still generate all four.

	Is there a way of customizing configurations
	without hacking cmake code.

Regards,
Nitin
