Help with documentation

[Brahmasmi]

Is there a way to figure out all the configurable switches/flags/parameters while compiling the codec?

I ask this because NE10 does not find a mention on the website or the README, but seems to be a useful flag while compiling for mobile platforms that support NEON.

In case there is an automated way of figuring out these switches/flags/parameters, please help me point to it (something like a "opus --help" or "man opus").
