I'm on Windows 11 and
I have openssl (OpenSSL 3.0.7 1 Nov 2022 (Library: OpenSSL 3.0.7 1 Nov 2022) and all the environment variables are configured too

The build error occurs when compiling src/c_helpers.c, which includes openssl/ssl.h. Check the project's build system (likely Cargo.toml and build.rs) to see how OpenSSL is located. On Windows, the openssl-sys crate may need proper environment variables or vcpkg. Look for existing documentation on building with OpenSSL on Windows. Verify the fix by running the build command that failed.
