pdfslicer: unvendor dependencies

[dotlambda]

I get

CMake Error at cmake-modules/Utils.cmake:4 (get_target_property):
  get_target_property() called with non-existent target "range-v3".
Call Stack (most recent call first):

Does someone know how to fix that?

According to https://stackoverflow.com/a/59035863/4446318 you would need to use add_library.

produces the exact same output

I poked at this as well, and couldn't get it to work (although I don't know anything about CMake). I suspect someone whose proficient with CMake could whip this into shape.
