Add a DLL to Qt Creator's run environment

[ChrisW67]

Select Projects, Run Settings, expand the Run Environment, and modify the PATH variable to include the GDAL binary folder
or
Arrange for the same change to be made to the system/user PATH variable in Windows

Thank you, that is what I was looking for. I thought that perhaps Qt Creator would have a config (*.cfg, *.inf, *.xml, etc) file where I could set library paths for the program, not just a particular project.

It didn't occur to me to modify PATH. I opted for the Build & Run Environment option instead of modifying the system environment because I want my workstation to have the same system environment as my users. Reduces the odds that I'll forget a file when deploying.

You can set the Windows PATH for a single user and base it on the system PATH. Just Add a user variable called PATH and set it to "c\some\other\path;d:\and \another" and this will be appended to the system's environment for that user.
