Add minimal CMakeLists.txt for IDE integration

Introduce a basic CMake configuration to help developers and
contributors import the project into IDEs and development tools that
rely on CMake for code navigation and build setup.

This CMake file is not intended as the primary method for building or
testing the project; the official build remains defined by the
Makefile.  It serves only to improve development workflow and tooling
support.
