When a project is configured with a 'strict manual' mode for object file destination directory, incremental build does not re-compile source files located in subfolders within the project. This happens only when the file's file-specific build-options are changed. But it does work if the file's contents are changed.

To reproduce:

1. import the attached project into workspace
2. build it once
3. modify any file-specific build-option on the f1/f1.c file
4. build the project
5. -> the f1/f1.c file is not re-compiled
