Compare with previous version

Currently there's a compiler error on my Raspberry Pi 400 with GCC.

vkcv-framework/modules/asset_loader/lib/fx-gltf/include/fx/gltf.h:86:9: error: narrowing conversion of ‘-1’ from ‘int’ to ‘char’ [-Wnarrowing]

It's related to fx-gltf though. So I tried to reopen a closed issue regarding that implicit conversion error which already appeared on Clang by another user.

If it does not get fixed, we might workaround it by removing the -Wnarrowing flag in some way. There's also a -Wno-narrowing flag which GCC allows. But it doesn't seem to workaround the problem. Maybe the -Wnarrowing flag gets automatically reset in the CMakeLists.txt of fx-gltf. Then we would need to rely on a fork or get a PR merged.

Raspberry Pi OS is only providing CMake 3.18.4. However adding slang has bumped the required version to CMake 3.25 recently.
