Enabling either of these modules results in additional downloading during
the configure stage of building.
+The face recognition module is enabled by default. This incurs an additional
+download of the face_landmark_model.dat file (~70M) from OpenCV's github
+repository during configuration. If this is not desired, the face module
+can be disabled by setting OCV_FACE environment variable to "no"
+e.g.
+ OCV_FACE=no sh ./opencv.SlackBuild
+
Documentation is generated by the SlackBuild unless it is switched off
by setting the CVDOCS environment variable i.e.
CVDOCS=no sh ./opencv.SlackBuild
