- Historically, GNSS-SDR linked against the GnuTLS library for cryptographic
functions. If GnuTLS was not found, then the building system looked for and
linked against OpenSSL as a fallback. This was due to the OpenSSL 1.x dual
license scheme, which was incompatible with GPL v3.0 license, preventing it
from being a mandatory dependency for GNSS-SDR in most GNU/Linux
distributions. This issue was solved with the release of OpenSSL 3.0.0, which
transitioned to the Apache License 2.0, fully compatible with GPL v3.0.
Accordingly, the GNSS-SDR building system now looks for OpenSSL in the first
place and, if not found, then it looks for GnuTLS as a fallback.
