you'll need to install docker for this to work
cd into the current directory. now use docker to build the app:
docker run --rm -it -v $(pwd):/work dmorgan81/rebble:latest build
now install it on your phone (adjust the ip address!)
docker run --rm -it -v $(pwd):/work dmorgan81/rebble:latest install --phone 192.168.2.103
Thats just for my IDE (CLion) to be happy and be able to find the headers for autocomplete. In case you use this too, copy "sdk-core" to the parent directory so that the parent contains sdk-core and this pride repository. the sdk-core can be obtained from https://raw.githubusercontent.com/aveao/PebbleArchive/master/SDKCores/sdk-core-4.3.tar.bz2
