# 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.
