In the project file (.pro) for your project, you can specify additional directories in the files system to search for header files using the following...

Source code

 
1
2

INCLUDEPATH += ../my/relative/path
INCLUDEPATH += D:/my/absolute/path


After making the change make sure you re-run qmake to rebuild the Makefile for your project.
Note the usage of all forward slashes. I think the use of backslashes has been deprecated even on the Windows platform.

Good luck!

Step 1: Find the required include files for the JSON stuff. If you cannot find where they are, then you cannot proceed.

Step 2: use the path you found in Step 1 and add that with the INCLUDEPATH.
