use OPENSSL_NO_ENGINE from OpenSSL config #4911

Open remicollet opened 1 day ago

remicollet commented 1 day ago

This fixes build on distribution where deprecated ENGINE are removed (e.g. RHEL-10-beta)

rand.h is needed for RAND_priv_bytes (was previously included from engine.h)

engine.h may be missing (ex: RHEL-10-beta), or empty (CentOS Stream 10, so upcoming RHEL-10.0)

Tested on

RHEL-8.10, OpenSSL 1.1.1k
RHEL-9.5, openSSL 3.2.2
RHEL-1.0-beta, openSSL 3.2.2 (no engine)
