    Description

      PCH compilation is failing when enabling pch in a subproject that is in a different directory than the main project. It appears that the incorrect path to the header file is given (ex: "pch.h" instead of "subproject/pch.h" or "/absolute/path/to/pch.h").

      I have attached a small project that show this issue.

      ~/Code/qbs_pch_subproject_issue$ qbs
Found project file /home/acossette/Code/qbs_pch_subproject_issue/qbs_pch_subproject_issue.qbp
