Cmake (#13)

* Using cmake target export

* CPack configuration

* Updated doxygen-awesome-css to v2.3.1

* Fixed wrong project title. Whoops.

* Removed "lib" prefix from project name, as CMake adds this automatically

* Updated maintainer information

* Updated README

* Added lib prefix to cpack package name

* Updated gitignore

* Added new "docs" target for HTML Doxygen generation

* Updated CPack config to generate .debs, .rpms, etc.

* Added new workflow
