Subject: [PATCH] meson/libmesa: ensure shader_replacement.h is generated
 before using it
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

By adding it to the list of files needed to compile `libmesa` instead of
relying on the racy "build this no matter what" mechanism which is
intended only for root nodes (≈ the binaries that we provide to users).
