It is used to know what program to call to drive an actual build after 
CMake generates a build system.

For a try-compile or try-run CMake needs to use the same environment to 
build the source files as that which will be used to build the generated 
project.  Otherwise the results could be inconsistent.

You probably cannot use the codeblocks executable unless it behaves 
exactly like devenv.  The VS project file generator is meant to work 
with the native VS tools.
