So, I am converting my project from qmake to cmake, and I'm just about done! However, I'm getting more than double the runtime speed on my qmake build, at least in debug mode. I'd like to have the same compile flags set in both build configurations so that I'm comparing apples to apples.
Unfortunately, I haven't had much luck figuring out what the heck is accounting for the performance difference! My qmake flags resolve out to this:

As far as I can see, these should see identical performance! Any ideas at all as to how my qmake build could be so much faster?
Edit: For even more fun, here is my qmake project file:

Edit: So, it's been a few weeks, and I've made absolutely no headway in figuring out what's going on here. I've generated some detailed reports for both build systems, which can be found here. So far, no clues that stand out to me. In fact, I don't even see anything in the reports that would suggest that my new build system is slower at all! If I'm reading things correctly, it should be faster.
Edit 2: Here are my linker options as well. The old way, and the new way.
