So, yeah, this is a meson bug, which I will work on (if this command ends up in

It looks like I've bumped into a variation of this bug. While attempting to
build the documentation for the latest glib2.0 release, I got the following:
FAILED: docs/reference/gobject/gobject-decl.txt

So @BUILD_ROOT@ didn't get replaced by the build root after pickling and
unpickling. Needless to say, this produced errors like:
cc1: error: @BUILD_ROOT@/glib: No such file or directory
[-Werror=missing-include-dirs]
I can give you a precise recipe for reproducing this bug if it would help your
debugging.
