Problem one: it requires its own binary, which we haven't built. There are instructions in sdl/src/hidapi/README.txt, if we ever want to try. Problem two: the Android app segfaults when `hid_init()` calls `g_JVM->AttachCurrentThread()`. This might be a bug in NDK 21's jni.h, but that seems unlikely. Perhaps a version mismatch? In any case, we aren't using the code at the moment, so the easy answer is to leave it out.
Submodule projects
Lime includes code from several other C/C++ libraries, listed below. Lime prefers to use GitHub repositories as its submodules, purely so that the links will be clickable when viewed on github.com. However, some of these repos are mirrors, with the development being conducted elsewhere.
Always submit issues and pull requests to the primary repo, not to a GitHub mirror.

Non-submodule libraries
In some cases, we use such a small fraction of a library that it isn't worth creating a submodule. This reduces download time but increases the difficulty of performing updates.
- PulseAudio | primary repo | GitHub mirror | Reason: only used on Linux, and only a few headers are used.
