[CMake] Installation corrupts library on OS X

[Peter Eastman]

Hi Clint,

You're absolutely right:

$ otool -l libOpenMMAmoebaCUDA.dylib | grep -A2 LC_RPATH
          cmd LC_RPATH
      cmdsize 32
         path /usr/local/cuda/lib (offset 12)
--
          cmd LC_RPATH
      cmdsize 32
         path /usr/local/cuda/lib (offset 12)

I'll try to figure out where the duplicate is coming from and see if that fixes it.

I'd be glad to report this to Apple, but I can't figure out how to reproduce the problem without using CMake.  I tried using install_name_tool to directly change all the paths myself, and that worked fine.  It didn't produce the problem.  Is CMake doing something different from just a series of calls to "install_name_tool -change" and "install_name_tool -id"?
