[cederom]

Description / Steps to reproduce the issue

• As found in build.yml[bugfix]:disable CMake Ninja for Msys2 #2671 the msys2 / cmake / ninja build is broken due to 8192 chars limit on command line length.
• Quick fix for the msys2 CI to use Makefile generator in place of Ninja is proposed here build.yml[bugfix]:disable CMake Ninja for Msys2 #2671.

A solution is required to fix builds on MSYS2 + CMAKE + NINJA.

I have some findings in this PR comments.
How about we disable Ninja on Msys until we fix this problem?
