I think my incorrect subject is symbolic of the fact that I don't know what
I'm looking for ;)

So you're basically saying that from cmake-gui on Windows, point C and CXX
to cl.exe? I did this but got a big fat error message:

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.

CMake Error: Error required internal CMake variable not set, cmake may be
not be built correctly.

Missing variable is:

CMAKE_C_COMPILER_ENV_VAR

CMake Error: Could not find cmake module
file:C:/Code/work/sandbox/cmake-gfe-dev/build2/CMakeFiles/CMakeCCompiler.cmake

CMake Error: Error required internal CMake variable not set, cmake may be
not be built correctly.

Missing variable is:

CMAKE_CXX_COMPILER_ENV_VAR

CMake Error: Could not find cmake module
file:C:/Code/work/sandbox/cmake-gfe-dev/build2/CMakeFiles/CMakeCXXCompiler.cmake

Configuring incomplete, errors occurred!
