This won't actually work since the filter is only applied when sources is
assigned to, and this is a more complicated regexp that is supported anyway.

I think this only applies to two files anyway so:
sources -= [
  "device/udev/device_manager_udev.cc",
  "device/udev/device_manager_udev.h",
]

Ditto here that this doesn't work.

Since this is a bunch of files, I'd actually delete this and move all of the
libgestures_glue files into the
  if (use_ozone_evdev && use_evdev_gestures) {
block (so the're never added in this else case).

Done.
