However, this does work if I add one more directory from the project root (i.e. if the variant directory is never under any directory in the relative path.)
The problem I think is in SCons/Node/FS.py:srcdir_duplicate().
Any time the variant build directory is under the one of the directories in the (relative include path), the path isn't further scanned to prevent reflection. Basically, because 'build' is under '..', search is halted, (because of the possibility that reflection would occur if the path is '../build/...' instead of '../include/...').
The attached modified test case which moves both src and include within another folder (so that 'build' is never under '..') works correctly with relative paths.
I think this is a bug as relative includes seem to be correctly supported (relative to the source file which has the include), except in the case where the variant build directory is under one of the directories in the include path.
