Bug#1069023: Using the library with cmake fails because of wrong path calculation in apriltagTargets.cmake

[Thorsten Jordan]

Package: libapriltag-dev
Version: 3.3.0-2.1

When using the library with cmake it doesn't work, because the file is placed one level of directories deeper than are unwinded in the cmake file.

See the patch below that fixes it.
