Compiler Doesn't Reuse Compiled Object Files Between Executables

This is needlessly spending time on recompiling widgets.
## Potential Solutions
- Flattening `CMakeLists.txt` to just go into one executable, but we're still in development here.
- (Shared) library with the widgets
  - As far as I know this wouldn't break the license terms
  - Could also make it do this by defining something in a `CMakePresets.json` or something
