Change Qt install path after building?

how can I change Qt install path after I building it ?

Example : qmake.exe search binaries to original install path, how can I change/redefine it ?

Thanks.

Edit : I finally found this patch to apply to Qt :

I was looking into this and found a way that works (in qt 4.7.2) by customizing qt with a qt.conf file.

In my case, I added a qt4-4.7.2/bin/qt.conf (I think it must be in the same place as the qmake executable)

With the following contents:

[Paths]
Prefix = c:/my_path/to/qt4-4.7.2

and the qmake -query started returning the proper paths!

See: http://qt-project.org/doc/qt-5.0/qtdoc/qt-conf.html for more details

You can change path to binaries and many other hardcoded paths in qmake using qmake -set command.
See Configuring qmake's Environment for details.

I can answer it for windows, not so sure about others. Remove the path variables if any present in the environmental variable PATH.

In Qt-Creator goto,

Tools->Options->Qt4->Qt Versions

In the right hand side area, you will find Auto- Detected and Manual. Under Manual add a new entry by clicking the + symbol in the far right. Specify the QMake location by clicking Browse . Change the Default Qt Version to your newly specified Version. Of course, you have to re -build the application. Hope that it helps.

On Unix/Linux:

You can also use LD_LIBRARY_PATH+PATH for workarounds. But still, some defaults are hardcoded in the code, yes. A rebuild is a must.

On unix you can make a symbolic link, otherwise you probably need to rebuild it

This worked for me with Qt 5.15.2:

cd ~/Qt/Tools/QtCreator/share/qtcreator/QtProject
grep -inr '<olduser>' | cut -d: -f1 | xargs sed -i 's/<olduser>/<newuser>/g'

Replace <olduser> and <newuser> obviously.
