A small utility that waits for a file to exist, optionally with some permissions.
Either via Docker:
$ git submodule update --init --recursive $ docker build -t zeit/wait-for .
or using CMake (requires Linux)
$ git submodule update --init --recursive $ mkdir build && cd build $ cmake .. -DCMAKE_BUILD_TYPE=Release $ cmake --build .
