"-fPIC" error while building qtsampleplayer on Ubuntu 16.04

I have this error while building qtsampleplayer:

I have used this command for cmake : ./cmake-2.8.11.2-Linux-i386/bin/cmake -DCMAKE_CXX_FLAGS="-fPIC" .. and also had edited the CMakeLists.txt of qtsampleplayer directory to add the -fPIC flag. The errors thrown by the code of libdash were removed by doing this but the qt is still throwing them. I have followed the instructions on README for installation of qt libraries.

Did you solve this problem? I faced the same problem.

I wasnt really able to solve it. What I did was:
Instead of running the command ./cmake-2.8.11.2-Linux-i386/bin/cmake, I ran cmake .. again and then make -j4. That worked fine for me and I was able to install qtsampleplayer.

@daemonslayer it really helps me solving it
