curl_easy_perform() failed: Unsupported protocol (WSS)

[Lifeda92]

I did this

1. Downloaded .ZIP from: " https://curl.se/download/curl-8.7.1.zip "
2. Builded using x86 Native Tools Command Prompt for VS 2019

set RTLIBCFG=static
nmake /f Makefile.vc mode=static vc=15 debug=yes

set RTLIBCFG=static
nmake /f Makefile.vc mode=static vc=15 debug=no

3. Added all dependends in project in properties.

4. Try using example code from: " https://curl.se/libcurl/c/websocket.html "

5. Got error: curl_easy_perform() failed: Unsupported protocol

I expected the following

Success using WSS protocol.

curl/libcurl version

libcurl version libcurl/8.7.1 Schannel WinIDN

operating system

Windows 10

WebSocket support is not yet enabled by default.

An option is coming up in 8.8.0 to enable it with this build method:
eb4fe6c #13232

Another way is the option -DENABLE_WEBSOCKETS=ON with CMake.
