# Find cppzmq
#
# Usage of this module as follows:
#
# find_package(CPPZMQ)
#
# Variables used by this module, they can change the default behaviour and need
# to be set before calling find_package:
#
# CPPZMQ_HEADER_PATH Set this variable to the location of the zmp.hpp
# header file if the module has problems finding it.
# ZeroMQ_INCLUDE_DIRS Set this variable to the include directories of
# ZeroMQ if the module has problems finding
# the proper installation path.
#
# Variables defined by this module:
#
# CPPZMQ_FOUND System has CPPZMQ header
# CPPZMQ_INCLUDE_DIRS The location of zmq.hpp header
# If we cannot find the header, we will switch this to false
set(CPPZMQ_FOUND true)
# Search for the header
find_path(CPPZMQ_INCLUDE_DIRS zmq.hpp
PATHS
${ZeroMQ_INCLUDE_DIRS}
${CPPZMQ_HEADER_PATH})
if(NOT CPPZMQ_INCLUDE_DIRS)
set(CPPZMQ_FOUND false)
endif()
if(CPPZMQ_FOUND)
include(IgnImportTarget)
# Since this is a header-only library, we should import it as an INTERFACE
# target.
ign_import_target(CPPZMQ INTERFACE)
# Now, to use the CPPZMQ headers, you should call
# target_link_libraries(<tgt> CPPZMQ::CPPZMQ) instead of using
# target_include_directories(~)
endif()
