# The main toxcore CMake build file.
#
# This file when processed with cmake produces:
# - A number of small libraries (.a/.so/...) containing independent components
# of toxcore. E.g. the DHT has its own library, and the system/network
# abstractions are in their own library as well. These libraries are not
# installed on `make install`. The toxav, and toxencryptsave libraries are
# also not installed.
# - A number of small programs, statically linked if possible.
# - One big library containing all of the toxcore, toxav, and toxencryptsave
# code.
