# 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.
