So a couple of things, this is happening because the CMakelists.txt in flightmarelib grabs the latest but if you follow the instructions and use python 3.6 you will run into this issue

Next, the cleanest way that got me past this particular hurdle was the following:

sudo apt-get update
sudo apt-get install -y libopencv-dev
cd flightmare/flightlib
rm -rf build
mkdir build
cd build
export OpenCV_DIR=/usr/local/share/OpenCV
cmake ..
make
