meson needs certain version

meson needs certain version

[Andy Tai]

Hi, I am trying to create package definition for some specific package
and it uses meson for build.   When I try to guix build the package,
it fails with

meson.build:1:0: ERROR: Meson version is 0.53.2 but project requires >= 0.54

I find meson later than 0.53.2 in guix already, but how in package
definition to specify to use a particular meson version?  Thanks

I use something like this in my guix.scm for a package that uses meson
and requires a version newer than 0.53.2

---8<---------------------------------------------------------------------------
(use-modules
  (guix build-system meson)
  …
  (gnu packages build-tools)
  )

(define-public foo
  (package
    …
    (build-system meson-build-system)
    (arguments
     `(#:meson ,meson-0.55))
    …
    ))
--->8---------------------------------------------------------------------------

Note that the defintion of meson-0.55 in the build-tools.scm has the
comment

;; Added temporarily for packages that need it.
;; TODO: Remove when core-updates is merged.
(define-public meson-0.55
…
)

So it might be safer to use meson-next to avoid breakage if/when
meson-0.55 gets removed.
