Building in MSYS2/MinGW + GCC 11.3 failed (1. ninja; 2. intrinsics)

[LigH-de]

1. Your build sequence documented in the repo's readme generates not a makefile but a build.ninja instead; so you may replace make by ninja.
2. Many files fail compiling, error messages relate to intrinsics. I guess this requires different configuration options? (I tested that in an interactive shell of an MSYS2/MinGW64 environment provided and kept up-to-date by the media-autobuild suite.)

Thanks for the report! I think we might need to add -msse4.1 compiler option to the relevant files..

I pushed commit befdf9c789c4e84738c359efdae10ce93c4a02ce to the master that should fix the issue, can you verify?

Edit:

...and 6b3dd245f6384716d7e55bfdbf99e89c6e2e7ad9 clarifies the README

Yes, ninja builds, and uvg266.exe --help prints a verbose parameter list.
