Not installing -> Outdated version of Qt - 4 Required(perhaps) - Have 5

All the steps of the tutorial were going along quite well, but when it came time for.. ...make I got the all the lines of output indicating something was happening, but the last few lines looked like this...

collect2: error: ld returned 1 exit status Makefile:117: recipe for target 'seven-square' failed make[1]: [seven-square] Error 1 make[1]: Leaving directory '/home/omar/sevensquare/build' Makefile:11: recipe for target 'app' failed make: [app] Error 2

And then using -> make install <- I get the error...

cp -vf build/seven-square /usr/bin/ cp: cannot stat 'build/seven-square': No such file or directory Makefile:14: recipe for target 'install' failed make: *** [install] Error 1

I have no idea how to fix this problem, maybe change my Qt version which is currently Qt 5.6.2 but I noticed the prior commands say qt4 and such.
