The underlying cryptography libraries describe here can be selected when
configuring CMake by explicitly setting JWT_SSL_LIBRARY
to one of three values. The default is to use OpenSSL.
- OpenSSL
- LibreSSL
- wolfSSL
Here's an example:
cmake . -DJWT_SSL_LIBRARY:STRING=wolfSSL
JWT-CPP relies on the OpenSSL API, as a result both LibreSSL and wolfSSL need to include their respective compatibility layers. Most system already have OpenSSL so it's important to make sure when compiling your application it only includes one. Otherwise you may have missing symbols when linking.
