Unable to build on Ubuntu 16.04

[MuhammadAsadJaved]

Hi, I am trying to build on Ubuntu 16.04. I am following these steps.

sudo apt-get install mesa-common-dev
sudo apt-get install libopencv-dev python-opencv
wget http://download.qt.io/official_releases/qt/5.9/5.9.1/qt-opensource-linux-x64-5.9.1.run
chmod +x qt-opensource-linux-x64-5.9.1.run
./qt-opensource-linux-x64-5.9.1.run

There is no error in this step. Then

git clone https://github.com/abreheret/PixelAnnotationTool.git
cd PixelAnnotationTool
mkdir x64
cd x64
cmake -DQT5_DIR=/home/littro/Qt5.9.1/5.9.1/gcc_64/lib/cmake -G "Unix Makefiles" ..
make

Here is the error in the make.

Then I also tried

cd scripts_to_build
sh build_linux.sh

but have the same error. Am I missing any step? Or what is the problem?
