Strange dependencies when compiling on MacOS

Hi!

I have tried to install Qt on my MacBook and an older desktop mac (G3 or something). They both compiled fine. And I could compile program code with it. But when I removed the folder I used to compile Qt in, it stopped working. Qt needed some of the files in the installation folder. This happened both on my laptop and the desktop computer. The only things I did to compile Qt was "configure", "make" and "sudo make install"... I thought that "make install" was supposed to move the needed files somewhere else than the installation folder.
I have also installed Qt on Linux and had no problem there.
