[CMake] MakeCommand unset in CTestConfiguration.ini

[kent williams]

OS X CMake 2.8.5

I was trying to get our nightly build script correct, and ran into this:


MakeCommand:
Cannot find MakeCommand key in the DartConfiguration.tcl

First of all we don't use Dart, there is no DartConfiguration.tcl in
the build directory. There is a CTestConfiguration.ini, which does
have this line:

MakeCommand:

Which is to say, the MakeCommand isn't set to anything.

What governs setting MakeCommand in the CTestConfiguration.ini file?
