# Requires these CMake modules:
|
||||
# FindPackageHandleStandardArgs (known included with CMake >=2.6.2)
|
||||
# COMPONENTS
|
||||
# ^^^^^^^^^^
|
||||
#
|
||||
# This module respects several COMPONENTS specifying the backend you prefer:
|
||||
# ``any`` (the default), ``libusb``, and ``hidraw``.
|
||||
# The availablility of the latter two depends on your platform.
|
||||
#
|
||||
#
|
||||
# IMPORTED Targets
|
||||
# ^^^^^^^^^^^^^^^^
|
||||
|
||||
# This module defines :prop_tgt:`IMPORTED` target ``HIDAPI::hidapi`` (in all cases or
|
||||
# if no components specified), ``HIDAPI::hidapi-libusb`` (if you requested the libusb component),
|
||||
# and ``HIDAPI::hidapi-hidraw`` (if you requested the hidraw component),
|
||||
#
|
||||
# Result Variables
|
||||
# ^^^^^^^^^^^^^^^^
|
||||
#
|
||||
# ``HIDAPI_FOUND``
|
||||
# True if HIDAPI or the requested components (if any) were found.
|
||||
#
|
||||
# We recommend using the imported targets instead of the following.

||||
#
|
||||
# ``HIDAPI_INCLUDE_DIRS``
|

# ``HIDAPI_LIBRARIES``
