VS: Add CMake input files to ZERO_CHECK
Add all cmake input files to the ZERO_CHECK
project. Place files
under CMAKE_SOURCE_DIR
in a folder structure matching the directory
structure. This way they are easier to find, and Visual Studio does not
close them when reloading the project.
Tested with VS 2017.
Fixes: #24557
