Yes, I understood the warning message. So, I could generate .bc files instead of .a files and that should fix the issue?
If that's the case, how do I tell CMake to build my libraries into .bc files instead of .a files using the toolchain file provided by Emscripten? And what is the difference between a .a and a .bc library file? Thank you!
