qmake is a tool that automates the genaration of Makefiles for projects (using Qt or not), i.e., acts as a build system tool. There is a whole section of the official Qt documentation dedicate to this tool. The idea behind this wiki page is to collect some material not present there yet and also tips & tricks that can be useful.
- Undocumented qmake, by Paul John Floyd. Although a little old, there is interesting stuff there.
