[Qt-creator] Downloading Kate Highlighter Definitions

[Jochen Becher]

Hi,

QtCreator says "SSL is not supported". But I have packages libssl1.0.0,
libssl1.1 and openssl installed on Ubuntu 18.04. Anything I miss?

Why doesn't Qt or QtCreator deliver their own packages if finding a
system install is difficult?

System Information:

qt.network.ssl: QSslSocket: cannot resolve CRYPTO_num_locks
qt.network.ssl: QSslSocket: cannot resolve CRYPTO_set_id_callback
qt.network.ssl: QSslSocket: cannot resolve CRYPTO_set_locking_callback
