How do I add an entire directory to a QT creator project

Question

I have an existing QT Creator project. I want to add an entire directory to this project. I see that I can right click in the project file browser tree and "Add Existing Files..." However through this dialog box, I can only add individual files. How can I include an entire directory?

Answer 1

Nowadays you can just right click on project name and select Add existing directory

Answer 2

qmake provides a convenient files function for this very purpose. Adding the following line to your project file will add .cpp files inside the src/ directory:

SOURCES += $$files(src/*.cpp)

By default, this is non-recursive. Setting the second parameter to true recursively finds all files:

SOURCES += $$files(src/*.cpp, true)

The files function was introduced since Qt 5.10.
