[libcamera-devel] [PATCH] meson: correctly pass the global include to the compiler

[Eli Schwartz]

It's not safe to assume `-include config.h` works, since this depends on
the functionality of the compiler that the cwd when running the compiler
is searched first.

When libcamera is included as a Meson subproject, the cwd of the
compiler is the cwd of the main project, not of libcamera's build dir,
and thus cannot be found. Instead, pass the include filename as a path
based on the current build dir.
