Fix devel/cmake-modules to it prefers "c++" over "CC" for compiling C++
programs

Related to bug 200475, which was about an exp-run with the "CC" alias for "c++"
removed from the base system, I noticed that even the latest CMake port still
prefers "CC" over "c++" whenever it can find it.

This is all due to a pretty old upstream commit in CMake:
https://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=7e58e5bb68cb058370b5015f576
ee5507e56facc

The commit message has: 'By default use "cc" for C, "CC" for C++, and "f95" for
Fortran.'

I would like to change the default for C++, and the order in which the
compilers are detected, as in the attached patch.  This only affects the
CMakeDetermineCXXCompiler.cmake module.
