I'm not sure if it's a bug

single run cmd：meson setup --buildtype=debug --pkg-config-path=/maxvision/opt/gstreamer/amd64/debug/lib/x86_64-linux-gnu/pkgconfig /maxvision/src/gstreamer/gst-template/builddir is ok
vscode + meson external is error

Start with the VS Code Meson external-command path and compare its logged `meson setup` arguments with the standalone command shown in the issue. Reproduce the failure on Ubuntu 20.04 using the provided Meson and VS Code context; done means the external invocation accepts the same options or reports a clear, corrected failure.
