That's because DEPENDS = "foo" actually means do_configure[depends] =
"foo".  This is so that packages can fetch/unpack/patch whilst their build
dependencies are being built.

Instead of adding a new task to run autogen which will run *before*
configure and therefore before your dependencies have been build, simply
do_configure_prepend() if the operations need to happen before cmake runs.
