Problem automatically linking with release version of qwt libraries

[dbrmik]

Hi

I am using eclipse under xp. I am having a problem automatically building a release application with the Qwt library using my Pro file. I have the following line in my pro file

LIBS += -lqwtd5 build debug version (default)

if I change it to

LIBS += -lqwt5 builds the release version

Everytime I need a release build I have to edit the pro file and change this

Is there a way of automating this, so that release builds automatically link with the correct release library

Thanks once again
