"""
Test that files are correctly located in the variant 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.

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
