This is my *.pro file, this pro file belongs to a project named or2d. This project file is in following path.
*.pro PATH: F:\VR_View\prashant.patel_CSLPCI\CSLPCI_CVOB\CSL\S RC\5.3.10\dev\src\vr\or2d.pro

In this project i am using some common files from other projects. Here "cooedit.cpp" is a common file, which lies in different folder. As I have to use *.pro file for linguist purpose, but i am not able to find strings from cooedit.cpp using "lupdate or2d.pro". How can i set path for files in different folders but belong to same project?

cooedit.cpp's path:
F:\VR_View\prashant.patel_CSLPCI\CSLPCI_CVOB\CSL\S RC\5.3.10\dev\src\vrlite\cooedit.cpp
