# - try to find libusb-1 library
#
# Cache Variables: (probably not for direct use in your scripts)
# LIBUSB1_LIBRARY
# LIBUSB1_INCLUDE_DIR
#
# Non-cache variables you should use in your CMakeLists.txt:
# LIBUSB1_LIBRARIES
# LIBUSB1_INCLUDE_DIRS
# LIBUSB1_FOUND - if this is not true, do not attempt to use this library
#
# Requires these CMake modules:
# ProgramFilesGlob
# FindPackageHandleStandardArgs (known included with CMake >=2.6.2)
