Details:


Using mexopencv <https://github.com/kyamagu/mexopencv>,
after addpath ('C:\mexopencv') I get in Octave 4.0.1+ (development branch) the
following warnings

warning: function .+cv\glob.m shadows a built-in function
warning: function .+cv\norm.m shadows a built-in function
warning: function .+cv\resize.m shadows a built-in function

after reporting this in mexopencv
([https://github.com/kyamagu/mexopencv/issues/239]),
it seems that the problem is with Octave implementation of namespace
functions. Since norm is in +cv forlder,
cv.norm refers to +cv\norm.m and norm refers to Octave's norm,
and there is no shadowing of built-in function
(see that discussion there).

Note that only root folder is added to the path and not +cv, (which cannot be
added). Note also that Octave does not recognize functions in
mexopencv\+cv\private (bug#45444).
