is an obvious mistake in cmake 3.7.0-rc2. The removal of the 'else()'
statement here and the substitution of the ' if(CMAKE_OSX_SYSROOT)'
defeats the prior handling of 'if("x${CMAKE_OSX_SYSROOT}" MATCHES
"/")'. This causes '-DCMAKE_OSX_DEPLOYMENT_TARGET:STRING=""
-DCMAKE_OSX_SYSROOT:STRING=/' to not be honored and -isysroot to be
emitted as a compiler flag universally.
