# This is an example of how to do a cross-build of OpenOCD using pkg-config.
# Cross-building with pkg-config is deceptively hard and most guides and
# paths refer to the build file system.
#
# This script is probably more useful as a reference than as a complete build
-# tool but for some configurations it may be usable as-is. It only cross-
-# builds libusb-1.0, hidapi and libftdi from source, but the script can be
