Windows build

Hi Jef,

I am looking for the windows build of the latest version of libdivecomputer. In the past you made windows builds where I could download the dll's. When I try this myself on either windows or linux via minGW, I am losing all support for USBHID, Bluetooth, etc. On linux it works fine if I install all the correct packages with headers.

Do you still have the pre-builds, or a solution how to build the windows dlls more consistently?

With kind regards, Vincent Hagen
