# libav can't be in SUBDIRS, because then automake will try to descend in it

# and find conditionals it doesn't know.
|

# so,
|
|
# - don't put it in SUBDIRS so automake doesn't descend
|
|
# - put it in DIST_SUBDIRS so make dist picks up the subtree
|
|
# - add an all-local hook so it does get built
|

# this also satisfies make distcheck
