/**
  * Finds the relative location of the project root.
  *
  * Used in tests which rely on the working directory - unfortunately Intellij and sbt have different default working
  * directories for executing tests from subprojects: while sbt defaults to the project root, intellij defaults to
  * the subproject.
  *
  * Previously a consistent behaviour was achieved by setting
  * `Test / baseDirectory := (ThisBuild / Test / run / baseDirectory).value`,
  * however that broke the bsp build within Intellij - it simply wouldn't recognise subprojects with this setting
  * any more.
