online installer Qt for chessx on Centos 6.4 compile with qmake

Using yum install qt has installed qt.i686 1:4.6.2-28.el6_5 to my /usr/share folder on Centos 6.5 but I need to follow these instructions to get chessx working: > To compile ChessX, you need Qt version 4.2.0 or above. 2. Compilation Compiling the source is simple. Execute: qmake and then make If the compilation is successful you should be able to run ChessX executable in bin subdirectory. It is called: chessx on Linux, chessx.app on Mac OS, chessx.exe on Windows 3. Problems If you have both Qt3 and Qt4 installed, verify that Qt4 is first on your path. You may check it, running: qmake -v But I don't know how to do the above exactly. chessx I have downloaded and installed in /usr/local/games as that seems logical to me.How do I set the path to make qmake work? Read "For simple projects, you only need to run qmake in the top level directory of your project." So the directory above chessx or qt4? NB: Since found out this is only to install locally where I was attempting to install remotely.
