#==================================
#
# - Find ZeroConf headers
#
#==================================
#
# The following environment variables are respected for finding Dnssd.
# CMAKE_PREFIX_PATH can also be used for this (see find_library() CMake
# documentation).
#
# DNSSD_ROOT
#
# This module defines the following output variables:
#
# DNSSD_FOUND - Was Dnssd and all of the specified components found?
#
# DNSSD_INCLUDE_DIRS - Where to find the headers
#
# DNSSD_LIBRARIES - The Dnssd libraries
#
#==================================
# Example Usage:
#
# find_package(DNSSD REQUIRED)
# include_directories(${DNSSD_INCLUDE_DIRS})
#
# add_executable(foo foo.cc)
# target_link_libraries(foo ${DNSSD_LIBRARIES})
#
#==================================
# Naming convention:
# Local variables of the form _dnssd_foo
# Output variables of the form DNSSD_FOO
#
