Compiling OpenAL Soft

Hello again! I am looking to add OpenAL to my project. I saw that audio was added in 4.1, but I'm not sure if it extended to Java 8, or if OpenAL could even be compiled. Has anyone tried this or have any tips for doing this?

CheerpJ 4.1 supports audio as provided by OpenJDK, by emulating ALSA APIs. OpenAL can conceptually be compiled, but similarly to gl4es it would require access to internal headers and libraries that are currently not released. It is almost certain the set of APIs currently implemented would also not be enough, so even more work on the kernel side of CheerpJ would be required. It our intention to make it possible for users to achieve these sort of things, but it is not a short term priority

That is completely understandable, I expected such. For now, I'll figure out how OpenAL works and write a version in Javascript that will work with LWJGL (2.9.3). Thank you for the info!

Figured I would change the title and tags since it is related and because I'd rather not bother people with a 3rd support post. I am attempting to compile OpenAL Soft with Cheerp, configured to only have the WaveFile and Null backends for testing purposes. When running cmake I get the following error: 
CMake Error: install(EXPORT "OpenAL" ...) includes target "OpenAL" which requires target "alsoft.common" that is not in any export set.
CMake Error: install(EXPORT "OpenAL" ...) includes target "OpenAL" which requires target "alsoft.fmt" that is not in any export set.
CMake Error in CMakeLists.txt:

  that is not in any export set.

I would have to assume that this is because there is no target for whatever Cheerp is set to target. Would there be a way to fool cmake into not throwing an error about an unknown target?

Fixed, just an issue with install locations.
