[CMake] Problems with LIBRARY_OUTPUT_PATH

[William A. Hoffman]

No, that is a bug.  Please report the bug.   The problem is that
you are using LIBRARY_OUTPUT_PATH slightly different than expected.
CMake assumes that LIBRARY_OUTPUT_PATH is either empty or set to the
same directory for the entire project.  So, cmake assumes that mylib
has the same LIBRARY_OUTPUT_PATH as mod and puts a depend line in
the makefile like this:

mod_DEPEND_LIBS = c:\hoffman\gal\build\plugin\mylib.lib 

Of course that file never exists.
