Allow User Configuration of RPATH Settings

[ahnaf-tahmid-chowdhury]

Description

This pull request introduces user-configurable options for controlling RPATH settings in the CMake build system. Previously, these settings were forced in the CMakeLists.txt file, leading to inflexibility and potential conflicts, as reported in issue #1001. By making these options configurable, users have more control over the behavior of RPATH settings during the build process.

Changes Made

• Introduce options for enabling macOS RPATH, skipping build-time RPATH, and building with install RPATH.
• Modify the logic to use user-configured options and provide feedback messages regarding the state of each option.
• Refactor the setting of install RPATH to be conditional upon whether the directory is considered a system directory.

Checklist

• The documentation has been updated.
• If the PR solves a specific issue, it is set to be closed on merge.

Additional Notes

• Please review and provide feedback.
• This PR aims to address the reported issue and enhance the flexibility of RPATH settings in the CMake build system.
