run testGtk.c for test
4. pkg-config
mkdir /opt/pkg -psudo wget tar xvf pkg-config-0.29.2.tar.gz cd pkg-config-0.29.2/./configure --prefix=/usr/local/pkg-config --with-internal-glibmakesudo make installpkg-config --version

5. ffmpeg
sudo yum -y install epel-releasesudo yum localinstall –nogpgcheck yum localinstall –nogpgcheck rpm –import rpm -Uvh yum -y install ffmpeg ffmpeg-develffmpeg -version
6. opencv dependencies

append at the end of file
