Fallback to using system cmake if chocolatey cmake not found

[mitchcapper]

I don't think this code was meant to stick around. If so maybe we should only use it if cmake cannot be found? That or we should provide some override for it.

Until I have a long term solution for #70 I still need this to build using AppVeyor

Can add a check like https://github.com/cefsharp/CefSharp/blob/master/build.ps1#L31 to make this an AppVeyor specific feature.

Ok how about this, uses the chocolatey cmake if it exists otherwise uses the system one.

Nice 👍

First build failed (https://ci.appveyor.com/project/cefsharp/cef-binary/builds/22164730)

Looks like it just needed an additional \bin\ to the path, follow up commit is 6af10e0

Build is working away, looks like it will succeed https://ci.appveyor.com/project/cefsharp/cef-binary/builds/22164969

Thanks for your help 👍

sorry about that, changed it for local testing and forgot to change it back.

Only real way to test it was to run an AppVeyor build, no big deal.

If you'd like write access to this repository then let me know, additional help is always welcome 👍
