Had to change because `openpnp-capture` converts all output to RGB (performance problem) doesn't re-enumerate after initialization (usability problem).
For some reason `wxChoice` on GTK frequently produces
```
*** BUG ***
In pixman_region32_init_rect: Invalid rectangle passed
Set a breakpoint on '_pixman_log_error' to debug
```
and displays incorrectly
Compiling the precompiled headers for `CemuCamera` took longer than compiling `CemuCamera` itself, so it just ends up being noticeably faster to just add it to one of the existing sublibs. It probably wasn't a problem for MSVC because precompiled header reuse works there, but I'm not using MSVC
