Bug #18763: The configure option “--with-openssl-dir” has lower precedence than pkg-config

I’m trying to compile Ruby 2.7.6 (latest stable release in 2.7 branch). In my environment, there are two OpenSSL installed, v1.1 and v3. The system pkg-config will find OpenSSL v3, but it isn’t compatible with Ruby 2.7, so I’d like to configure Ruby to link to OpenSSL v1.1 with --with-openssl-dir, but ./configure still uses OpenSSL 3 (that it found via pkg-config). Is this expected? If so, how am I supposed to override the OpenSSL directory?

This issue has more details: https://github.com/postmodern/ruby-install/issues/412

So CRuby picks a mix of of 1.1 headers and 3.0 lib, when given --with-openssl-dir.
That sounds like a clear bug.

Setting PKG_CONFIG_PATH helps but this is not intuitive, --with-openssl-dir should be enough on its own.
