In fact i know well the error, as i devel with Qt in my office under
Windows and MSVC.

You need to launch the MSVC terminal, not the standard Windows
terminal (aka "cmd").

This MSVC terminal init a lots of variables to be able to use the CLI
compiler from Microsoft (i hope that you install the CLI MSVC tools
with the Mircost compiler installer).

You will found the MSVC terminal in Run Windows menu, MSVC section,
and advanced tools (or something like that). There are many version,
to cross compile to ARM or in 32bits. for get these ones, and take the
native 64 bits version.

Voilà.
