This is the community-supported CMake build system for libusb project.
The officially-supported build system for libusb remains Autotools, as part of the libusb main repo.
NOTE: libusb/ subfolder is a git subtree. Do not attempt to contribute to it - use an upstream libusb repo for that purpose.
The main use case as of this moment - using libusb as a subdirectory. Depending on the needs of the host project libusb may be built with different options, with or w/o installing binaries, etc.
More details: TBD.
