Build using CMake

[robertbartel]

Refactor build setup to use CMake build system. Add targets for stand-alone driver (mainly for testing), BMI shared library, and test executable with existing, simple test routine.

Additions

• New top-level CMakeLists.txt

Removals

• Makefiles in src/ and test/

Changes

• Modify test code to dynamically get test data directory as macro that CMake build provides, to support running tests from CMake build directory
• Modify test data so that tests can successfully be run from CMake build directory
• Have git ignore JetBrains IDE project directory
• Updating GitHub Actions workflow configs to account for new build setup

Testing

1. All build targets all succeed
2. Test executable with previously existing tests runs when called from CMake build directory
3. All existing test pass
