Summary:                    CMake needs to support building against "/" on OS X
with a deployment target set
Description: 
CMake doesn't allow setting -DCMAKE_OSX_DEPLOYMENT_TARGET="10.8" together with
-DCMAKE_OSX_SYSROOT="/".

According to an Apple engineer that's a problem/flaw. See also the whole
discussion at
  https://trac.macports.org/ticket/44125
(If you are able to CC others, please add 'jeremyhu' at macports . org to this
ticket.)

I'm attaching his patch that is currently being used in MacPorts:
   
https://trac.macports.org/browser/trunk/dports/devel/cmake/files/patch-Modules-Platform-Darwin.cmake.diff?rev=122338


Steps to Reproduce: 
Run
   cmake -DCMAKE_OSX_DEPLOYMENT_TARGET="10.8" -DCMAKE_OSX_SYSROOT="/" ...
on any CMake-based project. The build always fails, complaining that
CMAKE_OSX_SYSROOT should also be set.
