what is the relationship about cmakelists and VS project?

[motatamotata]

I create a VS2015 project from a cmakelists file, and there is a problem I do not understand, in cmakelists file I set:
OPTION(SUITESPARSE "Enable SuiteSparse." OFF)
Then I build a project through VS2015, it works fine, but I don't know in vs project where is the code(or setting, or macros？) to corresponding to "OPTION(SUITESPARSE "Enable SuiteSparse." OFF)".

Thanks a lot!
