Solved installing on Windows

I could not install opencv4nodejs on Windows 11 with node 16, npm 8, and Visual Studio 2019 build tools.

I downgraded to node 14 and npm 6.

I had Visual Studio 2017 build tools installed with 2019, but the installation looked from 15.0 in the 2019 folder.

I uninstalled 2019 tools, repaired 2017 from the VS Installer, and successfully installed openvs4nodejs from Developer Command Prompt for VS 2017.

I found this https://github.com/justadudewhohacks/opencv4nodejs/issues/717 alternative to uninstalling 2019.
