[poco:netssl] mixing NetSSL_Win and NetSSL_OpenSSL?

[ghosttie]

Please forgive me if this is stupid, I'm a C# developer using vcpkg (and C++) for the first time.

From #18238 it seems that vcpkg builds NetSSL_Win and not NetSSL_OpenSSL for Poco. However I wasn't able to do

vcpkg install poco[netssl]:x64-windows --recurse

without first doing

vcpkg install openssl:x64-windows

And now that I've got Poco built, I'm getting a runtime error (read access violation) in \vcpkg\buildtrees\openssl\x64-windows-dbg\ssl\ssl_lib.c because Poco::Net::Context is passing OpenSSL a null SSL_CTX.

My theory is that it's mixing NetSSL_Win and NetSSL_OpenSSL versions of the classes, so that even though I've created the Context (what I believe is) correctly, I've created a NetSSL_Win context that it's trying to use with OpenSSL.

Is there a way of telling whether vcpkg is using NetSSL_Win or NetSSL_OpenSSL? Looking in \vcpkg\buildtrees\poco\src\5e947b89f9-22a3da2471.clean there are both NetSSL_Win and NetSSL_OpenSSL folders.
