Compile with OpenCV 4.0

[alyssaq]

docker run --name py3 --rm -it jjanzic/docker-python3-opencv bash

Must include -I/usr/local/include/opencv4

Eg gcc -pthread -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -fPIC -I/usr/local/include/python3.7m -I/usr/local/lib/python3.7/site-packages/numpy/core/include -I/usr/local/include/opencv4 src/hat.cpp -o build/temp.linux-x86_64-3.7/src/hat.o

Current error:

In file included from src/stasm.h:58:0,
                 from src/hat.cpp:8:
src/misc.h:420:1: error: ‘CvScalar’ does not name a type
 CvScalar ToCvColor(unsigned color);

Nope. Couldnt import with OpenCV 4.0.1:

Python 3.7 with OpenCV 3.4.1 was OK.
