[Qt-creator] Generating QtCreator cmake project for given CMakeLists.txt from command line

[Tobias Hunger]

Hi Nikolaus,

Thanks for the instructions! I just managed to do a successful catkin
build (outside of Qt Creator for now:-)

My first impression is that it will be tricky to fully integrate the
catkin_tools workflow, even simple things like figuring out how to map
source and build directories or even find the full path to files that
compiler warnings are about. I will need to poke around a bit before I
dare to make suggestions on how to support this though.

Best Regards,
Tobias

There is also catkin_make, which has a different approach in that it adds a top-level CMakeLists.txt to your workspace and builds all packages in one giant CMake project. This makes QtCreator integration easier, since there is just one project to import with one build directory. But the catkin-tools workflow has many advantages and is meant to eventually replace catkin_make as the default workflow: https://github.com/catkin/catkin_tools/issues/90

With 3.6.1 I actually sill have an issue where `include_directories` is not properly propagated to the code-model such that QtCreator does not find include files. This is in conjunction with catkin. But I haven’t had that issue in 4.0 yet, so I stopped to investigate.
