[CMake] need help fixing warning message... 3.0

[J Decker]

if it exists as a target; I need to know the path to the built library for
subsequent projects to link against.  I have to manually add the option
-L<path to build library) -lbaselibname to avoid having the full path
linked into the resulting .so.

if I just use 'add_link_library' then the resulting library will not load
except on the system that built it, because the library name references
contain paths to the libs not just the libname.
