Compiling on windows
You can crosscompile blackmagic for windows with mingw or on windows with cygwin. For compilation, headers for libftdi1 and libusb-1.0 are needed. For running, libftdi1.dll and libusb-1.0.dll are needed and the executable must be able to find them. Mingw on cygwin does not provide a libftdi package yet.
To prepare libusb access to the ftdi device, run zadig https://zadig.akeo.ie/. Choose WinUSB(libusb-1.0) for the BMP Ftdi device.
Running cygwin/blackmagic in a cygwin console, the program does not react on ^C. In another console, run "ps ax" to find the WINPID of the process and then "taskkill /F ?PID (WINPID)".
