Extension using Meson as build system

Hi hackers,

Is there any extension that uses meson as build systems?
I'm starting a extension project that written in c++, cmake is my
initial choice as the build system, but since PostgreSQL has adopted
Meson, so I'm wondering if there is any extension that also uses
meson that I can reference.

any extension from contrib package

https://github.com/postgres/postgres/tree/master/contrib

probably only these

Regards

Pavel

Ah, yeah, but I'm not sure these extensions have any dependencies
on the main project? Never mind, I'll take a look, thanks.

any postgres extension has dependency on main project

what can be different - if the extension is build inside or outside source
code tree

Take contrib/ltree as an example, in Makefile, there are some lines:

ifdef USE_PGXS
PG_CONFIG = pg_config
PGXS := $(shell $(PG_CONFIG) --pgxs)
include $(PGXS)
else
subdir = contrib/ltree
top_builddir = ../..
include $(top_builddir)/src/Makefile.global
include $(top_srcdir)/contrib/contrib-global.mk
endif

I am taking these as the reason that extension can build outside of postgres
source code, but I can't find an equivalent in meson.build.

https://github.com/postgres/postgres/tree/master/contrib

probably only these

probably nobody did it yet
