[cmake-developers] Apple tests for target_link_libraries failing

[Bill Hoffman]

I am running your test right now...


I do get these warnings:

CMake Warning at

Does that have anything to do with this?



Here is the link line:

Do you have a suggestion of where to put some mark up in cmTarget.cxx or 
other places in the code to see where this is coming from?
