Summary:                    CMake should support default installation of
Xcode.app only, without 'command line tools' extras
Description: 
Nowadays, Xcode is distributed as a standalone .app instead of an installer that
copies files all over the place.  As a consequence of this, nothing gets
installed at /usr/bin/make, /usr/bin/cc, etc.  Those programs are still
included, just not at those locations; instead, they are within the Xcode.app
bundle somewhere.

Optionally, one can install a separate 'command line tools' package that places
things at those venerable locations.  Without installing that, one can still
find and use 'make' and other tools using 'xcrun' (see 'man xcrun').  ex:

$ xcrun make --version
GNU Make 3.81

$ xcrun -find make
/Applications/Xcode.app/Contents/Developer/usr/bin/make

Without the 'command line tools' installed, CMake seems unable to get far:

Error(s) when configuring the project
CMake Error: CMake was unable to find a build program corresponding to "Unix
Makefiles".  CMAKE_MAKE_PROGRAM is not set.  You probably need to select a
different build tool.

It would be nice if CMake could support having only Xcode.app and not the
'command line tools' extras.

Suggestions:
 - invoke 'xcrun -find' to find the paths to the tools it needs.
 - invoke 'xcrun <tool name>' to invoke the tool.
