Subject: Added OPENSSL_LDFLAGS env variable which is appended to SSL checks.
X-Git-Tag: release-2.0.18-stable~7
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=92781968475c7553a08f5b4161f1df631c6ef01f;p=libevent

Added OPENSSL_LDFLAGS env variable which is appended to SSL checks.

If openssl is not installed system-wide or not compiled as a shared library,
some systems require various link flags (e.g., -ld).
