+LibUSB cmake notes
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+On Windows, cmake does not have the advantage of pkg-config,
+so we must manually tell cmake how to locate the LibUSB header and lib.
+
+From the cmake gui, select "Advanded View":
+
+* Set LIBUSB_INCLUDE_DIR to the directory with "libusb.h".
+* Set LIBUSB_LIBRARIES to the full path for "libusb-1.0.lib".
+
+Then check the boxes to enable USRP1 support, click configure and generate.
