This is a pretty simple question that I imagine has a very simple answer.

I built a GDAL library on my workstation to work with shapefiles in my Qt app. After a day of troubleshooting and learning, I've sorted out building and compiling via customizing my .pro file.

However, when I attempt to run the program from Qt Creator, it crashes immediately because it is missing a gdal-specific DLL (gdal19.dll). This is relatively easily fixed by copying gdal19.dll into my build target, but I'd rather not have to do this every time I rebuild or start a project. How would I tweak Qt Creator's Build & Run environment to link to a custom DLL at a fixed location on another drive?

Qt Creator already links to the Qt DLLs stored elsewhere, so I imagine that this must is a simple setting somewhere that I simply don't know.
