I am look for a good book or website that clearly explains the basics of using make, (particularly qmake for Qt development) makefiles, etc. for building C++/Qt executables. I am using open source tools on Ubuntu.

Lately have been doing a lot of Qt/C++ development using the CodeLite IDE, which works quite well with Qt, however when I wanted to write my own QObject derivatives with custom signal and slots, I discovered I had to use qmake and I don't know how. (Meanwhile I have been using QtCreator, which handles this, but it not my IDE of choice)

I have several books on C++ and Qt but I haven't found that they focus at all on this area.

Recommendations please...
