* Adds microphone controls on Linux via PulseAudio (PA) for several
points in
https://github.com/OpenVR-Advanced-Settings/OpenVR-AdvancedSettings/issues/43.
It can not be overstated how unsuited the public AudioManager API is for
using the PA API.
It can also not be overstated how undocumented and horrible the PA API
is. The PA way of doing audio is very unlike the Windows way of doing
audio, which the AudioManager is heavily influenced by.
Since I don't have a Linux machine I have not been able to personally
test this. https://github.com/feilen/ has graciously helped with
testing.
PulseAudio is very undocumented and not very widely used for what we
need outside of official utilities. As such there's most likely a better
way of doing things than I've done.

The "complex" PA API is asynchronous. Since our current AudioManager is
running synchronously and would not work asynchronously (functions are
expected to return valid data on function return) it is necessary to
massage the PA API until it runs synchronously.
This is done with a general workflow of
1. Register a callback function (`pa_context_get_source_info_list()`,
for example).
2. Run the PA loop through `customPulseLoop()`. This will trigger
any registered callbacks. Sometimes a `void*` is passed through the
callback that can be used for custom data. `successCallback()` uses
this to set the success variable.
3. Run the callback function and do required work.
4. Return to original function, do work or return values.
It is not possible to run a `customPulseLoop()` inside of an already
running loop (inside a callback), as this will lead to a PA assert
error on runtime.
Enabling the switch on release builds will optimize the binaries as
normal, but will still include debug symbols. This is advantageous for
bugs that do not show up in debug builds without optimizations.
The page was not made with Arch in mind.
The currently required were tested on Manjaro, more packages may be
explicitly required due to the bare-bones nature of Arch.
Adds simple logging calls makes debugging easier.
The initial build script was basically ported over directly from
Windows. It was written because I at the time didn't understand
compiling on Linux, and the existing standards, very well.
Moving as many build components into a program specifically made for
building C++ makes everything much easier.
The old build script is still used on CI where control flow can only be
changed using environment variables.
`bear` and `clang-format` are only used on the CI, there's no reason to
include them here.
This enables a `sudo make install` that copies the build directory to
the PREFIX directory (/opt/OpenVR-AdvancedSettings/AdvancedSettings by
default).
The entire directory is being copied because Qt is incredibly weird
about how the INSTALLS variable works. From testing it appears that only
files that exist before the build process has started (even the
file_copy process) will be eligible for installation.
If the /OpenVR-AdvancedSettings/ directory is excluded, Qt will attempt
to remove the /opt/ folder on `make uninstall`, this is obviously not
desirable.
