I'm using the C API with CMake, built from the command line. One relatively minor issue I'm hitting is that the Playdate SDK's CMake files have it build a project's pdx in the root of its source directory.
On top of it being a bit odd to have a build artifact be created in the source directory rather than the build directory, this means that I can't easily have builds for both the simulator and device at the same time, since building for one always overwrites a previous build for the other. Of course I could just copy the pdx file around between builds, but I'd rather they just be created in a build directory specific for either the emulator or physical Playdate so I always know which one I'm dealing with.
I just edited playdate_game.cmake
to allow this, but it means that if I update the SDK I'll have to make the change again. It'd be nice to have a CMake variable that just specifies where the pdx is going to end up, and seems like it'd be a pretty straight forward change to make.
(In fact if I have working changes to playdate_game.cmake
that allow this, would you like me to just send you my changes somehow?)
