libxml2/meson.build
Nick Wellnhofer b0fc67aa22 build: Remove --with-tree configuration option
This option would allow for a smaller, but mostly useless minimal build.
But it complicates the symbol availability logic in an insane way and
requires specialized tools like our custom C parser in doc/apibuild.py.

See #717.
