I tried to build the example, described on your blog (link), and I got the following errors.

Is there any way to solve these issues ?
Bonus questions:
Did you ever thought or start to develop some toolchains management for cmakepp ?
My use case is aimed for building cross-platform unity3d plugins for iOS, Android, WSA, MacOSX and Linux of CMake driven project (eg. Tensorflow)
More precisely, it would be really cool to manage a list of toolchains like Polly and some dockerized transpilers like with Dockcross.
It would help to create a template through cmake, as I would like to create a build bot to replace such bash scripts:
