I am new in the community and I would like to ask a question. I have written an application in c++ with QT that I can compile and use on my linux distribution. However, I cannot use the binary file on another computer which is normal because the libraries are different. Using the ldd command on my aplication, I see that shared libraries are the following:

I would like to include these libraries in my application to be able to use it on another computer.
I don't know if i have to use it as static or shared and I do not care, I just want it works :).
I have tried adding them in my .pro file on QTcreator by the following way (examples with libgvc):
unix:!macx: LIBS += -L$$PWD/../../../../usr/lib/ -lgvc
INCLUDEPATH += $$PWD/../../../../usr/lib
DEPENDPATH += $$PWD/../../../../usr/lib
The compilation goes well. However, it still does not work on another computer like if libraries were not included in the binary file.
I also tried to add the following commands:
QMAKE_LFLAGS += -static
LIBS +=-Wl,-Bstatic
But in this case, I get an error message during compilation
Cannot find -lgvc
Do you have an idea of how I can compile my program as standalone on Linux with Qt creator?
