Setting LD_LIBRARY_PATH from Qt Creator

[spud]

Hi all,
I'm having problems with something that should be very easy.
I have a project which creates a dynamic library and an executable. So far I have only compiled it on Windows and I use the following setup:

#Library pro file
TEMPLATE   = lib
DESTDIR    = ../lib
DLLDESTDIR = ../bin
DEFINES   += CREATE_DLL
CONFIG    += debug_and_release
 
build_pass:CONFIG(debug, debug|release) {
    TARGET = $$join(TARGET,,,d)
}

#Library pro file
TEMPLATE   = lib
DESTDIR    = ../lib
DLLDESTDIR = ../bin
DEFINES   += CREATE_DLL
CONFIG    += debug_and_release

build_pass:CONFIG(debug, debug|release) {
    TARGET = $$join(TARGET,,,d)
}

To copy to clipboard, switch view to plain text mode 

#Application pro file
TEMPLATE     = app
DESTDIR      = ../bin
LIBS        += -L../lib
CONFIG      += debug_and_release
 
CONFIG(release, debug|release){
    LIBS    +=  -lMyLib
}
build_pass:CONFIG(debug, debug|release){
    TARGET   = $$join(TARGET,,,d)
    LIBS    += -lMyLibd
}

#Application pro file
TEMPLATE     = app
DESTDIR      = ../bin
LIBS        += -L../lib
CONFIG      += debug_and_release

CONFIG(release, debug|release){
    LIBS    +=  -lMyLib
}
build_pass:CONFIG(debug, debug|release){
    TARGET   = $$join(TARGET,,,d)
    LIBS    += -lMyLibd
}

To copy to clipboard, switch view to plain text mode 

Now I want to debug the application on Linux with Qt Creator. I'm using Ubuntu.

I load the project into Creator and I can compile it just fine in debug or relase mode. The problem arises when I want to launch the application.

Failed to start program. Path or permissions wrong?

I can start the app from a terminal if I call

export LD_LIBRARY_PATH=/path/to/lib
ldconfig

export LD_LIBRARY_PATH=/path/to/lib
ldconfig

To copy to clipboard, switch view to plain text mode 

But setting LD_LIBRARY_PATH from within Qt Creator has no effect.
I could of course fix it by setting LD_LIBRARY_PATH globally before I start Qt Creator, but that isn't convinient, since I have a lot of projects with the same setup.

So I was wondering if someone could tell me what the cannonical way is to set up your pro files for a project using dynamic libs(in a portable way). None of the examples or demos from Qt use dynamic libs(not counting plugins, since they're a differnt story alltogether).

I'm greatful for any help and apologize beforehand for my linux noobishness.
