You need to compile kdelibs 3.5.8 first, as kdebase depends on it.
Concerning the qt dependency, you seem to already have one version installed on your system and the found version seems to satisfy the configure script : Qt (>= Qt 3.3 and < 4.0). So why do you want another one?
And you didn't say what Linux distribution you are using and why you want to compile kde yourselves. Don't you have a package manager to install binary packages ?
To force to use your qt version, check if you have this file :
If you have it, try :
./configure --prefix=/home/kde1/ --with-qt-dir=/home/qt --with-qt-include=/home/qt/include --with-qt-libraries=/home/qt/lib
If you have not it, I think your qt installation is not complete.
But you must compile kdelibs first, before kdebase, trying to use the commands given above with the kdelibs configure script.
An easier way is to install kde binary packages using a package manager.
