I had to build FFmpeg with x264 support on macO statically, so I had to look around for a bunch of scattered commands. This is why I thought I should gather them up into a single post for easier reference later on. Here’s the result.

Qt provides an extremely simple mechanism for deploying applications on macOS, thanks to macdeployqt tool. Unfortunately, the same does not apply to Qt for macOS applications that reference 3rd party libraries such as OpenCV. In this post, I’ll describe the manual but simple process of adding 3rd party libraries into macOS Application packages in order to eliminate the need for installing those libraries on our target computers.

Following up on this post from last year, I’d like to share a couple of simple scripts that you can use to build OpenCV 3 or 4 on Windows, macOS and Linux operating systems. Needless to say, they require CMake and proper build tool sets on each platform.

This guide is quite similar to my previous How-Tos about building OpenCV from source codes and using them in Qt, but I wanted to created a fresh one and point out a few of the changes made in this recent OpenCV version that requires you to reconfigure your Qt projects just a bit.

In recent versions of macOS, such as macOS Mojave you might receive a warning message keeping you from running Picture Stamper (or any unregistered 3rd party application) on your computer. Here’s how you can allow it.

Here is what you need to add to your Qt qmake projects to be able to add and use OpenCV 3.4.1 default set of libraries. I usually add them into a separate *.pri file and include that in my *.pro files to avoid repetition, but that’s up to you. Well, here it is:
