Unsolved Qt Creator not stopping at breakpoints

[kitfox]

I'm working on an opensource project that uses cmake to build it's project. I'm able to compile and build the project, but when I try to run it in debug mode and set a breakpoint, the debugger ignores it.

I'm pretty sure that the project is being built with debugging symbols (at least, the CMAKE configuration has it's debug flag set). I'm also building for debug mode based on the icons on the bottom left of the QT Creator window. Is there anything else I should check that may be stopping the debugger from stopping at my breakpoints?
