Comment (by NicosPavlov):

 Alright, so I checked again, and I don't know what happened the first
 time, but removing the -DOPENAL_INCLUDE_DIR and -DOPENAL_LIBRARY variable
 from the PortGroup works.

 In that case, it finds the proper SDK:
 {{{
 Found OpenAL:
 /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/System/Library/Frameworks/OpenAL.framework
 }}}
 based on configure.sdk.

 So the solution would be to suppress the paths in the PortGroup, and check
 for configure.sdk, and set it to "/" if it is empty.

 I just need to check which ports in the KDE PortGroup would be affected by
 that change.
