Summary:                    CMake generates “-L/usr/local/lib” on Mac OSX
Description: 
Could you please help me with the question I asked on the mailing list.
http://public.kitware.com/pipermail/cmake/2015-August/061413.html. The question
is also pasted into Steps to Reproduce for convenience. 

I'm still at loss what triggers CMake to generate -L/usr/local/lib linker flag. 

Steps to Reproduce: 
I have a CMake C++ dylib project that builds correctly in one MacOS X
environment but fails in another. Environments are on the same machine, but
under different users. I'm seeking help how to do I troubleshoot where the
failure in the second one comes from.What I managed to figure out is that in
failing configuration CMake adds the following flags in link.txt (the commands
used to link the executable)-arch x86_64

-isysroot 
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk

-mmacosx-version-min=10.6

-L/usr/local/lib
The last one causes havoc as it makes ld pick up dependencies from
/usr/local/lib instead of link directories I configured in CMake.I would
appreciate any insight what triggers generating the flags above and what is the
best way to squelch them, especially -L/usr/local/lib?
