-# FIXME: How do we know, at the point where the _build_cms are run, that the
-# $(host_prefix)/include/libsnark folder is there? The lifecycle of that folder
-# is as follows:
-# 	1. First, the _stage_cmds of libsnark.mk create it in the staging directory.
-#	2. At some point in time, the depends system moves it from the staging
-#	   directory to the actual $(host_prefix)/include/libsnark directory.
-#
-# If (2) happens after the libzerocash_build_cmds get run, then what's in the
-# $(host_prefix)/include/libsnark directory will be an *old* copy of the
-# libsnark headers, and we might have to build twice in order for libzerocash to
-# get the changes. If (2) happens before, then all is well, and it works.
