add LGPLv3 linking exception for header-only GR4
Browse files Browse the repository at this point in the history
This commit adds the LGPLv3 linking exception to handle GR4 as a header-only library. The exception allows proprietary applications to link and use GR4 without disclosing their source code, addressing legal and operational constraints (e.g., in government or security-sensitive applications).

This is particularly important since traditional dynamic or static linking isn't applicable in header-only libraries. Modifications to GR4 itself remain LGPL-compliant, ensuring continued adherence to copyleft and FLOSS principles while enabling wider adoption.

By including this exception, we aim to increase the flexibility for adoption by public organisations, critical infrastructure, and industry partners, while maintaining the core FLOSS principles.
