Research direction

Start by inspecting the build script’s SDL3 system-library setup and the dvui SDL3 backend header cited in the error, zig-pkg/dvui-0.5.0-dev-AQFJmWiB-gCtzdvo-D5qGOj-k7nNvIsFEq-nYctwzDvZ/src/backends/sdl3-c.h. Compare the include paths used by zig build -fsys=sdl3 with pkg-config --cflags sdl3; done when the system-SDL3 build succeeds.

Written by the indexing model from the issue text.

Description

It seems there's something wrong in build script with dvui setup? I cannot build with zig build -fsys=sdl3 which results in the following error.

$ zig build -fsys=sdl3

Pkg config shows sdl3 headers correctly.

$ pkg-config --cflags sdl3
