Create a Continuous Integration workflow

[sisco0]

A Continuous Integration (CI) workflow needs to be added by the use of Github Actions. In this way, the project quality would grow as now, the project could be compiled without any doubts under Dockerized images and Binary Artifacts could be created for Windows 64 and Linux when using Statically Linked builds.

This should be accomplished after #2.

• Create the CI build system using Github Actions for CMake based on Linux.
• Add Windows to the build system output.
• Add Darwin to the build system output.

Showed evidence of implementation at https://github.com/sisco0/aquaminer-gpu/actions for the feat/ci-build-gpu-cpu branch. The CUDA package has been setup, but could not find the branch where OpenCL is used for some reason (not visible for me), so the WITH_GPU parameter is a dummy configuration for the linux branch yet.

Submitting my Pull Request for this subject to move forward on the first Task.
