Problems trying to build opencv in python: "-- Configuring incomplete, errors occurred"

Question

I'm trying to install openCV in python

I have the same problem as mentioned in those several github and stackoverflow pages but I'm still stuck:

github openCV issue #8382

github openCV issue #6027

github openCV issue #6066

Here is an ouput of the terminal:

mymacs-MacBook-Pro:build mymac$ cmake -D CMAKE_BUILD_TYPE=RELEASE 
>     -D CMAKE_INSTALL_PREFIX=/usr/local 
>     -D INSTALL_C_EXAMPLES=OFF 
>     -D INSTALL_PYTHON_EXAMPLES=ON 
>     -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib/modules 
>     -D BUILD_EXAMPLES=ON ..

  The cmake-policies(7) manual explains that the OLD behaviors of all
  policies are deprecated and that a policy should be set to OLD only under
  specific short-term circumstances.  Projects should be ported to the NEW
  behavior and not rely on setting a policy to OLD.

Answer 1

As mentioned on this here I tried checkout the same version for opencv_contrib that I did for opencv by running the following command:

cd ~
cd opencv
git checkout 3.0.0
cd ~
cd opencv_contrib
git checkout 3.0.0

It worked

I then ran the command make -j4

but the two following error messages appeared:
