cmakepp errors on MacOSX + bonus questions

[roscopecoltran]

Hi,

hope you are all well !

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

1. eigen3 is not included
2. several CMake Warning

Errors:

  Cannot set "__ans": current scope has no parent.
Call Stack (most recent call first):
  /opt/local/share/cmake-3.7/Modules/Compiler/Clang.cmake:7 (return)

This warning is for project developers.  Use -Wno-dev to suppress it.

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:
