Add BUILD_DEBIAN_PACKAGE option for Debian package support

Introduced the `BUILD_DEBIAN_PACKAGE` CMake option to enable building a Debian package for the library.
When this option is enabled and the host system supports Debian, the library will be packaged accordingly.

Usage:
To enable debian package building:
`cmake -DBUILD_DEBIAN_PACKAGE=ON <other_config_options> ..

To build debian package:
`make package`
or
`cpack`
