The conventional solution to this is to run cmake in the "build/debug"
directory.

I think that's outside the scope of the Makefile generator. For that
generator, CMAKE_BUILD_TYPE is a configuration-wide setting. If you
want a different configuration, you need a different build directory
(where "build directory" is wherever you run cmake).
