[CMake] ExternalProject autotools with MSYS from a MinGW root project

[David Demelier]

Hello,

I was guessing if it is possible to build a autotools based project
that requires MSYS from a MinGW project.

The ExternalProject could works but using the MinGW generator in the
root projects requires to *not* have the sh.exe in the PATH.

So I'm stuck on how to achieve this.

Do you have any ideas/recommandations?

Regards,
