FindOpenSSL: Search for -pthread flag
Because -pthread
doesn't begin with -l
, it doesn't show up in the
pkgconfig LIBRARIES variable, causing FindOpenSSL
to not add the
Threads::Threads
dependency. Explicitly search LDFLAGS_EXTRA
for -pthread
and add the dependency if it's found.
Fixes: #24532 (closed), !8230 (merged), !7986 (merged)
Backport: release
