I frankly don't understand why that failed to work.  Completely static
executables are possible with cmake.  I know this because I made one several
months ago as a temporary experiment.  Look carefully at your make output.
I am virtually positive your link step is missing the -static option for
some reason (or else you have some stale older results interfering; make
sure you start with an empty build tree.)

If after reviewing that evidence, you still cannot figure how to impose the
-static link flag with cmake, I suggest you prepare the simplest possible
(i.e., "hello-world") example (which after all, normally links to libc) and
give us the complete details (CMakeLists.txt, hello-world.c, and complete
cmake and make results) of that example so we can figure out where you are
going wrong.
