[PATCH 009/132] libqemuutil: convert to meson

From:	Paolo Bonzini
Subject:	[PATCH 009/132] libqemuutil: convert to meson
Date:	Thu, 12 Dec 2019 13:50:53 +0100
This shows how to do some "computations" in meson.build using its array
and dictionary data structures, and also a basic usage of the sourceset
module for conditional compilation.

Overall the look of the meson.build code is quite good, however Meson
doesn't enjoy the same flexibility we have with Make in choosing
the include path.  In particular the tracing headers are using
$(build_root)/$(<D); for now my solution is to generate headers like
"trace/trace-audio.h" and have sixty one-line forwarding headers in the
source tree; for example "audio/trace.h" includes "trace/trace-audio.h".
I'm not sure if it's possible to instead add a one-line "generate
trace headers" directive to each subdirectory's meson.build file.
I suspect that it _is_ possible but you'd still have to change the
include directives to include the subdirectory name (and then I prefer
the forwarding headers).

The overall lines delta would be negative if it weren't for the forwarding
headers.

directly in
 the sub-directory that uses them. The only exception is where there are some
 shared trace events defined in the top level directory trace-events file.
 The top level directory generates trace files with a filename prefix of
-"trace-root" instead of just "trace". This is to avoid ambiguity between
+"trace/trace-root" instead of just "trace". This is to avoid ambiguity between
 a trace.h in the current directory, vs the top level directory.
