[CMake] rebuilding technique

[Jon W]

How should a visual studio developer rebuild individual projects
within the ide?  It has been mentioned on the alias that one should no
longer use the visual studio "rebuild" option as that also rebuilds
the cmakelists.txt.

Is the only way to rebuild source files without rebuilding
cmakelists.txt to go and delete the desired directory within the
binary directory?

Thanks,
Jon
