[CMake] Main program not getting rebuilt when library changes.

For some reason, the ALL_BUILD project was *not* selected/checked to build.
However if I build it explicitly or
change the VS configuration so it does build, the main program is still not
being re-linked.

>Another thing to try is to run cmake --build . and see if that works.
That appears to compile the lib cpp file and rebuild the library just fine
but it also doesn't re-link the main program.
I've copied the output from "cmake --build" below in case that is of any
use.
