Hi Gary,

looks like some incomplete libraries are left over from previous failed 
builds. You can force a re-build of everything like this:

$ cmake --build ~/wsjtx-prefix/build --target install --clean-first -- -j

The --clean-first deletes all intermediate products before the build 
starts, the -- passes further arguments to the underlying make tool and 
the -j tells make to build stuff in parallel across multiple CPU threads 
(makes build go a lot faster).
