Added basic Cmake support for Linux and Mac with Windows coming soon

[makepath-alex]

Simple usage would be:

git clone <repo>
cd <repo>
mkdir build
cmake -S . -B build
cmake --build build --config Release -- -j8

This would build the basic libraries in Release configuration

If you want to also build and run the tests, you have to enable the ENABLE_TESTS option, which if OFF by default.
You can do it like so:

cmake -S . -B build -DENABLE_TESTS=ON

Then build as usual

To run the tests, go inside the build folder and tun ctest, for Example:

ctest -v

Note that for compiling the tests you need netcdff and for running them successfully you would also need the rrtmgp-data repo

Initial windows support done. To operate on Windows you need to work through a conda environment for the build process.
Basic instructions:

Install conda

https://docs.anaconda.com/miniconda/install/

Go to the location where you would like the conda env to reside
Create an empty conda environment like so:

mkdir -p env
cd env
conda create -p .

Activate the environment

conda activate ${PWD}

Install required packages

conda install -c conda-forge gfortran netcdf-fortran ninja gcc cmake

Build the repo:

cd <REPO>
mkdir -p build
cd build
cmake -G "Ninja" .. -DENABLE_TESTS=ON
cmake --build . --config Release

Run tests:

ctest -V

@makepath-alex Please update your branch with changes from develop in the main repo; this will turn off CI that isn't working.

Can you please modify containerized-ci.yml to use CMake? I might have to add CMake explicitly to the container.

Can you add Windows CI using CMake? I could try to help if need be.
