+Test that files are correctly located in the build directory even when
+Scons does not have a global view of all targets.
+
+Sometimes, it might be interesting to not tell scons about every
+targets. For example, one might not read in all the SConscipts of a
+hierarchical build for a particular invocation of scons. This would be
+done to speed-up a partial rebuild when the developer knows that only
+a subset of the targets need to be rebuilt.
