 5 | ## Status
 6 | 
 7 | This is an as-is, unsupported, proof of concept. No help is available.
 8 | 
 9 | ## Notes
10 | 
11 | For a real-world application, see https://github.com/openkneeboard/openkneeboard
12 | 
13 | * Xaml-related header files **must** be listed as targert sources
14 | * The `Directory.Build.targets` file is currently required; it slightly modifies the CMake generator
15 | * I've avoided `use namespace` to be explicit; I'm not aiming for this to be 'best practice', just to be unambiguous and minimal
16 | * `pch.h` and its' contents are required by the generated code
17 | * `pch.h` is not currently a pre-compiled header
18 |
