[Qt-interest] QMake equivalent to ./configure --prefix

[Merwin]

Hello,

I'm developping a console application, with plugins support. I've got a 
main.pro project file with a subdir template. I'm looking for a way to 
specify an 'install directory', that means that all the subdirs projet 
(in fact, plugins) will be installed in this directory.

For example:

qmake dir=/home/me/myapp/
make
make install

And make install will install all files in /home/me/myapp.
And the plugins (which are SUBDIRS project), would install in 
/home/me/myapp/plugins/.
I didn't found an easy way to do this, is there one?

Thanks,
--
