Summary:                    CMake fails to identify the Cray compilers' version
numbers
Description: 
As demonstrated below, CMake 3.0.1 fails to identify the version of the Cray C,
Fortran, and C++ compilers.  CMake 3.3.2 and CMake 3.4.0-rc3 exhibit the same
behavior.  This bug is also archived at
https://github.com/sourceryinstitute/AdHoc/tree/master/src/cmake.

Steps to Reproduce: 
> cat CMakeLists.txt 
project(cray_compiler_version_bug LANGUAGES Fortran C CXX)
if(
   "${CMAKE_Fortran_COMPILER_VERSION}" MATCHES "" AND 
   "${CMAKE_C_COMPILER_VERSION}"       MATCHES "" AND 
   "${CMAKE_CXX_COMPILER_VERSION}"     MATCHES "" 
  )
  message(FATAL_ERROR 
    "CMAKE_Fortran_COMPILER_VERSION, CMAKE_C_COMPILER_VERSION,
CMAKE_CXX_COMPILER_VERSION are all empty."
  )
endif()

> mkdir build && cd build

> FC=ftn cmake ..
