+- 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.
