Whenever I try to build WebKit on Windows through Powershell 7 using

perl Tools/Scripts/build-webkit --release

it fails to build and throws me an OpenSSL error, even though a Windows port of OpenSSL is installed on my computer and its root directory is specified in my system environment variables.

Here’s my full terminal output:

I checked my environment variable for OpenSSL, and the value of OPENSSL_ROOT_DIR is set to C:Program FilesOpenSSL-Win64bin. I also tried looking for similar Stack Overflow posts but to no avail.

I don’t really know much about WebKit or OpenSSL, so any help here would be greatly appreciated.
