libudev is linked explicitly and only a few structures need to be declared which are passed as pointers to the dynamically loaded functions. No need to require libudev-dev on the build machines.
- Replace hidapi/linux/hid.c with the hidraw variant (link to udev)
- Add CMakeLists.txt for hidapi, refactor
- Add udev rules file (no installation so far)
Implemented using hidapi library (https://github.com/libusb/hidapi) and https://github.com/koenieee/CrossplatformSpacemouseDriver/tree/master/SpaceMouseDriver as reference
Unsolved issues:
- When manipulating the SpaceNavigator wxWidgets generates a mouse wheel event that needs to be filtered out
- wxWidgets does not detect devices being connected/disconnected to the pc
- Current state forces a continuous rendering
- Current state misses dependence on camera zoom
- Non intuitive movement limits
- Translation and rotation speed factors are hardcoded
- Number of device buttons hardcoded
