Subject: [PATCH] Accepting request 1061506 from
 home:alarrosa:branches:multimedia:libs

- Add patch to reduce the required meson version to 0.61.0 since
  that's what we have in SLE 15:
  * reduce-required-meson.patch
- Probably because of a problem in SLE's meson, the generated
  pkgconfig files are missing some variables that are needed by
  rpm to generate the pkgconfig(...) provides correctly. In order
  to fix this, we now check for those variables and insert them
  in the pc files before installation if they're missing.
