When building with alire, I get on each and every build a warning:
..\alire\cache\dependencies\gnatcoll_22.0.0_620c2f23\gnatcoll.gpr
254:7 warning: value "windows" is not used as label
This warning cause GNATstudio to open the gnatcoll.gpr file, bring it into focus, and show the line containing the issue.
This distracts enormously!
Could you please make an update (22.0.1) that doesn't have this warning?
