How to debug a qmake/pro file?

[Defohin]

I'm trying to learn more about qmake and pro files and I'm having a bad trying to understand the return of a few variables, for example, how to debug and see what is returning from _PRO_FILE_PWD_ or after the usage of $$replace, etc?

message($$_PRO_FILE_PWD_)

You can also run qmake in debug mode (with additional message and information) by calling it with -d or -d -d switches, e.g.

qmake -d myproject.pro
