# Findlibusb
# --------
#
# Try to find libusb library and headers.
#
# IMPORTED Targets
# ^^^^^^^^^^^^^^^^
#
# This module defines the :prop_tgt:`IMPORTED` targets:
#
# ``libusb::libusb``
# Defined if the system has libusb.
#
# Result Variables
# ^^^^^^^^^^^^^^^^
#
# This module sets the following variables:
#
# ::
#
# LIBUSB_FOUND True in case libusb is found, otherwise false
# LIBUSB_ROOT Path to the root of found libusb installation
#
# Example usage
# ^^^^^^^^^^^^^
#
# ::
#
# find_package(libusb REQUIRED)
#
# add_executable(foo foo.cc)
# target_link_libraries(foo libusb::libusb)
#
# Early return if libusb target is already defined. This makes it safe to run
# this script multiple times.
if(TARGET libusb::libusb)
