When we do an in-tree-build with autotools and an out-of-tree build
with meson (all in the same source directory), then we have the
following files:
libnm-core/nm-core-enum-types.h
libnm/nm-enum-types.h
build/libnm-core/nm-core-enum-types.h
build/libnm/nm-enum-types.h
This caused "tools/check-docs.sh" for `ninja -C build test` to fail,
because the files are detected twice:
--- command ---
/data/src/NetworkManager/tools/check-docs.sh /data/src/NetworkManager /data/src/NetworkManager/build
--- stderr ---
8a9
> nm-core-enum-types
38a40
> nm-enum-types
*** Error: libnm classes not included in docs/libnm/libnm-docs.xml ***
-------
Try to make check-docs.sh script more readable.
Also, previously the script would check that one side was a subset
of the other side. Tighten this check up, now both sides of the
comparison must agree and yield the same lines.
