#1428 Implement cmake-file-api support

[Ben S.]

Kitware has marked CMake's Code::Blocks generator as deprecated and threatened to remove it in future releases: https://cmake.org/cmake/help/latest/generator/CodeBlocks.html

They are encouraging IDEs to instead implement native CMake support via their cmake-file-api: https://cmake.org/cmake/help/latest/manual/cmake-file-api.7.html

Native CMake support would also make for a better user experience, as users could directly open/import a CMake project instead of having to run CMake separately before being able to use Code::Blocks.
