I have cmake installed and in path.

Steps to reproduce

1. Run scons.

Minimal reproduction project

No response

'cmake' is not recognized as an internal or external command

you have to install cmake

[Anutrix]

I have cmake installed and in path.

Like I said before cmake is in path. Tested it by just running cmake in the terminal too.

[Anutrix]

The path all seems to be hardcoded for *nix systems(i.e, with /).

Perl and NASM seems to be needed to compile openssl. Additional it should be run in an MSYS2 shell.

[mattkanwisher]

It appears their CI uses Ubuntu Linux to compile windows. If you have visual studio 2022 and use Git Bash environment Cmake will be found. However there are other issues with hard coding of Pathing styles inside the python code

"mkdir -p C:\Users\hyper\Documents\LamProject\webrtc-native\deps/build/build.windows.template_debug.x86_64.Release.dir/openssl
The syntax of the command is incorrect."

This error tricky to fix cause this thing really only runs in a unix like environment, but its getting some default path that is a windows style path with backslashes and then appending forward slashes to it

[Anutrix]

Some issues got fixed in #74.

As of #100 it should be possible to build using MSVC (worked on my machine ™️ with Visual Studio 2019 and 2022).
You will need to install nasm and add its location to the PATH environment variable.
You will also need a valid perl installation (tested with Strawberry Perl, which in my case didn't require adding to PATH but YMMV).

MinGW builds might need some more work in upstream godot-cpp (see godotengine/godot-cpp#1147).
