Windows: Build updates

- Generate rc files from version.rc.in + CMake variable information in CMakeLists files
- Add step to generate .lib file for windows developers
- Re-structure tool flag usage, apparently ADD_DEFINTIONS adds them to _ALL_ tools. This is bad for rc files with the windres tool.

Needs other platform testing, as the flags have changed to fix Windows rc file generation.
