[CMake] Unexpected recompilation with ctest compiled MSVC project

[Simon Rit]

Hi,
If I do two consecutive builds with the same project, then it does not
recompile the second time, no. It behaves as if something is different (a
flag or something else) between the command line ctest build and the build
in the gui.
