# Purpose of 3rdParty This directory is used to download and build dependencies for BOINC components. Archives should be downloaded into a platform specific subdirectory (e.g linux, mac, ...) to allow cross compilation of several platforms on a single host. Build products of dependencies should be installed into a corresponding subdirectory of 3rdParty/buildCache to allow CI systems to cache this data between BOINC builds. See the existing [buildLinuxDependencies.sh](buildLinuxDependencies.sh) and [buildMacDependencies.sh](buildMacDependencies.sh) scripts for how this is done on Linux and Mac currently.
