We need a platform-independent way to specify where is the WOLF project, so that code can locate relevant files at tun-time.
We need a platform-independent way to specify where is the WOLF project, so that code can locate relevant files at run-time.
For example, if we want to use YAML files for configuring sensors, `YAML::LoadFile(filename)` needs an absolute path to a `filename`. This name is platform-specific, and many times user-specific.
Usually, these files are out of the WOLF project. But for testing purposes, some of these files exist within the WOLF directories.
