git revision description only trigger rebuild of one file

I've been using your git revision description module. Works great!
If I understand this module correctly, it watches files in .git/
and then copies them to CMakeFiles/
which then triggers a rebuild.
Since it triggers a complete rebuild, I simply include the description variable as a preprocessor macro.
I'm wondering if there is a way to trigger a rebuild of only one file. Perhaps have a git_revision.cpp.in
that looks like
#include "git_revision.hpp"
const static std::string git_revision = "@git_description@";
and git_revision.hpp
#ifndef GIT_REVISION_HPP
#define GIT_REVISION_HPP
const static std::string git_revision;
#endif
and only trigger a rebuild of git_revision.cpp
when a committ, pull, etc. occurs.
Any ideas?
