Install and Link Third Party Libraries in Qt Application
I'm building a Qt application which also use OpenCV (and this in turn, is built with support for Intel TBB). So far I have worked with my installation of OpenCV in "/usr/lib" and "/usr/include" on Linux and in "C:\opencv" on Windows.
Now, I want to work with all the libraries I'm using contained within the home directory of my application. So, I created a directory '3rdparty' in which I created a directory opencv. Within this last directory, I put the OpenCV include files and dynamic link libraries for the opencv modules I'm using; namely core, imgproc and highgui (.so for Linux and .dll for Windows, each group in a corresponding subdirectory).
My doubts are:
Is right I want to do ?, that is, to want to have all external dependencies of my application hosted "local" to put it one way.
I need to copy the dynamic link library file (.so / .dll) to the directory where my application is built. How can I specify that in the .pro file?
Regarding this question (and as I've never done anything like this before), I think the copy of the files should be made before running the QMake's generated makefile, because the application must link to those libraries ... I'm wrong?.
How can I specific such thing in the .pro file?
- What are the rules for link such library files, considering the point in my previous question?
Thanks in advance for any help and/or suggestions.
You don't need to copy the libraries to link to them. You can simply add the 3rdparty include + lib paths to the corresponding variables in you pro file.
