I think that it is need to avoid using runpath when installing openal-info for OSX.

$ otool -D /usr/local/Cellar/openal-soft/1.18.2/lib/libopenal.1.18.2.dylib
/usr/local/Cellar/openal-soft/1.18.2/lib/libopenal.1.18.2.dylib:
/usr/local/opt/openal-soft/lib/libopenal.1.dylib

libopenal.1.18.2.dylib may be correct.

The runtime path should be cleared by cmake when installing the executables. @rpath/libopenal.1.dylib could just indicate that it looks for it in the default library paths (on top of any runpath that may or may not be set) instead of a hard-coded one like /usr/lib or /System/Library/Frameworks. And since it looks like libopenal.1.dylib was installed in /usr/local/Cellar/openal-soft/1.18.2/lib or /usr/local/opt/openal-soft/lib or something, if the system doesn't know to look in that path for libraries that would explain why it can't find it.
