I'd first try using the --with-openssl= configure option before
manually patching in workarounds.

Or if you must patch, I'd probably hack in custom paths just before
"FindRequiredPackage(OpenSSL)" in CMakeLists.txt rather than the
configure script.  If you're patching source code directly and still
have problems, it's hard to help further unless you give the exact
patch you are using.

I think you were setting the compiler fine, but sounds like now the
OpenSSL headers not being found is likely a separate/unrelated issue
to figure out.
