Error specified source space '/home/xxx/src ' does not exist when using Qtcreator

Today, Ubuntu,ros and Qtcreator are newly installed, and they occur at compile time.

22:42:45:starting: "/opt/ros/hydro/bin/catkin_make"

Base Path:/home/xxx

The specified source space "/HOME/XXX/SRC" does not exist

22:42:46:the process "/opt/ros/hydro/bin/catkin_make" exited with code 1.

The error, that is prompted to develop the source path under "/home/xxx/src", but in fact my path is ~/catkin_ws/src below. After checking the build setting it feels like there's a problem with build environment. Finally found the PWD, his value is/home/xxx/. After changing him to/home/xxx/catkin_ws/, the compiler passed. PWD is actually the base path where the compiler appears.
