Hi, I am currently developing a qt sub directory project. This is the structure:

Root Project:
Root.pro
Subdir Project:
Subdirapp.pro - TEMPLATE = app
Subdirlib1.pro - TEMPLATE = lib
Subdirlib2.pro - TEMPLATE = lib
Subdirlib3.pro - TEMPLATE = lib
Subdirlib4.pro - TEMPLATE = lib

First, I would like to ask how can I create a shared library for the subdirectory projects(Subdirlib1.pro,Subdirlib2.pro,Subdirlib3. pro and Subdirlib4.pro).
Second, I would like to ask how can I link those subdir projects using this shared library allowing me to use UI and functions of every

Upon building the projects. ".a" and ".dll" were generated.
I am currently working on MINGW build configuration.

I really need your help guys! Please.
Thanks in advance
