-Subject: [PATCH] gstgl: Fix build when Meson >= 0.58.0rc1
-
-"implicit_include_directories: false" now also means that current build
-directory is not added to include paths by default any more. We have to
-add it manually because we have some custom_target() that generate
-headers in current build directory.
-
-See https://github.com/mesonbuild/meson/issues/8700.
