+Subject: [PATCH] meson: Generate cmake config and version files if meson is
+ new enough
+
+Meson 0.50.0 added a module similar to the pkg-config module for
+generating cmake config files. Since the CMake build system provides
+these the meson build system should as well.
+
+v2: - Bump version to 0.50 instead of incorrect 0.49
+v3: - remove TODO comment that this fixes
+    - Add a definition of set_and_check for meson-generated Config
+      files.
