any more. The developer now needs to know to also install the "Command
Line Tools" in addition (or in leau of*) Xcode.

proper version of Xcode. Beyond that we are getting to the point that
Windows is at where one is expected to have a fully functioning Visual
Studio Command Prompt for CMake to generate Visual Studio Projects. A
pain yes, but a fact of life.

cmake-gui to date has no platform specific code in it...  We could have

Sure there is, and the word on the web for all other people wanting this 
compiler is to do just that.  A quick google search shows this:

Basically, where did gcc go?  You need to install the command line 
tools...  Seems to be the question and answer spinning around the web. 
This was a HUGE change by Apple to make the command line tools not 
install by default with Xcode.  That is my opinion and I stand by it.. :)
