I do not think so, the condition definitely says "AND NOT MSYS" - so that would
use the Unix method.

Ah, but the issue is that under MinGW-w64/MSYS2 things are installed in
different directories and possibly a different structure than under Windows
with MSVC. MinGW-w64/MSYS2 is a bit of a hybrid system, though leaning towards
the Unix way.

Thanks, it looks like some more experimenting is required.
