 When compiled the first time, it will automatically download and build its [external dependencies](#Required-Build-Tools-External-Libraries).
 This takes a while, but only has to be done once. If the defaults in the build do not work for you, and you need to set specific make parameters, you can save them in `Make.user`. The build will automatically check for the existence of `Make.user` and use it if it exists.
