Subject: CMakeDetermineCompilerId: Use CMAKE_VS_(DEVENV|MSBUILD|MSDEV)_COMMAND

In the code path for launching the VS IDE tools, avoid using
CMAKE_MAKE_PROGRAM.  Instead use the variables CMAKE_VS_DEVENV_COMMAND,
CMAKE_VS_MSBUILD_COMMAND, and CMAKE_VS_MSDEV_COMMAND to lookup the
location of the build tool needed.  Choose the proper tool based on
availability and necessity for the language (e.g. Intel Fortran must
build with devenv.com and not MSBuild.exe).
