Subject: [PATCH] chore: version is 0.0.1

This PR sets the version for the initial 0.0.1 MrDocs release. To ensure the versions in header files are always consistent, version details like major, minor, patch, and build are dynamically populated during the build process from variables defined in the CMakeLists.txt file.

Adjustments have been made to include paths to ensure the new dynamically generated Version.hpp file is correctly included during the building process and installed with other header files.
