Has nothing to do with your question, but: don't use file(GLOB) for project 
sources. See the documentation why this is a bad idea.

Please look into the library dir for the .lib file and tell us it's name, then 
we may get a clue why this is not working. Until it is fixed you can go to your 
build dir and do

cmake -D RUBY_LIBRARY=c:/ruby/193/foo/bar/baz.lib .
