CMakeLists.txt

# NOTE: This file was added in order to build it with GH Actions, and in an
#       effort to have an initial CMake setup. Any community help to improve
#       it and make it easier for external projects to use it would be
#       appreciated.
#       This CMakeLists.txt and the one in the examples/cmake directory were
#       both created using this excellent Git repository as reference:
#       <https://github.com/pr0g/cmake-examples/>.
