[CMake] CMake 2.8.8 : Reproducible Crash in Mac OS X 10.8

[Michael Jackson]

I am going to be *very* pedantic here so you may slap me upside the head. The compiler was never "just there" on OS X. It has *always* required the installation of the developer tools. With 10.8 it would seem that installing "Xcode" is not enough to get the command line tools any more. The developer now needs to know to also install the "Command Line Tools" in addition (or in leau of*) Xcode.

About the best CMake-Gui could do is detect you are on OS X 10.8 or greater and ask the developer if they have in fact installed the command line tools or used Xcode-select (or what ever it is) to select the 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.


* There is actually a separate download for the command line tools that it looks like it could be installed without Xcode though I have not actually tried this myself.

Have a nice weekend.

That said we will try to make cmake print a helpful message or work out of the box.  I am just wondering how other projects are handling the sudden disappearance of the compiler from the command line...  (it has been there since the very first OSX Mac...)
