Custom suffix not working correctly for dylibs


I would like to make a dylib from the Projucer with a custom suffix. Let’s say instead of foo.dylib.

According to the in-app help for the Binary Name field this should be possible:

The filename to use for the destination binary executable file. If you don’t add a suffix to this name, a suitable platform-specific suffix will be added automatically

However, if I add in that field, the resulting binary has dylib appended anyway, so I end up with

Any suggestions?
