qmake to cmake, are there any tools to help automate this?
-
Hey folks, so I'm a total noob to cmake, and I'm trying to convert my current qmake setup over (since I figure that it has to happen sooner or later). However, I my qmake has a bunch of weird stuff in it that I'm not sure how to convert over:

Can I print out messages similarly? Can I add to my DEFINES, LIB, INCLUDEPATH, and all those other variables the same way? Is there something similar to CONFIG? What about my MOC_DIR, OBJECTS_DIR, etc? And how would I override flags like with QMAKE_CXXFLAGS ? I don't even know where to start, it's all a bit overwhelming.

Hi,
A quick search showed that Kitware has such a script for the base things.
There's likely something as well in the dev branch of Qt since Qt 6 uses cmake as build system.

@SGaist Thanks, but I feel like it would be more work to learn and set up Ruby than it would be to attempt this by hand. I did find this script, but I'm not sure if there's any documentation on it, or if it even works properly. I'll give it a go, it'd just be nice to be able to sanity check things.

AFAIK, it's the script that was used to bootstrap the port from qmake to cmake so it should do a pretty good job.
