I just discovered drone.io and docker images and it is very interesting.
I have a public C++ project that uses cmake 3 to configure. I would like to use drone as my CI platform. I manage to download and compile cmake 3 from source and then configure and compile my project. However, I would like to know if is it possible to store the compiled cmake somewhere and avoid to compile it for each build. I read about cached directory but I do not understand how to use it and if this is the best solution.
Thank for your help!
