{cmake} Updates for target-based approach 

- instead of setting globals which can effect other projects including this as a subdirectory, set them on the target if possible
- add "CONFIGURE_DEPENDS" to GLOBs to check for changes
- update required CMake version to 3.12 (still ancient - 2018) to support these
