4 years ago You can solve this problem by doing a recursive git clone.
git clone --recursive
If you already cloned use the following command to fetch all the submodules :
it submodule update --init --recursive --remote
The tiny library and rapidjson folders are empty which causes the build to fail.
I simply downloaded the repositories and placed the files in the respective folders but it would be nice if the documentation instructed this.
