  I managed to get this working by reinstalling Qt from scratch, and this time specifying 64-bit MSVC as the compiler, instead of 32-bit. There really isn't a 64-bit version of the compiler--there's only one installation package for Visual Studio, and it winds up in C:\Program Files (x86) on a 64-bit system, but it includes 32-bit and 64-bit debuggers. I had chosen 32-bit when originally installing Qt, because I wanted to make sure I'd get the same 32-bit executables regardless of which machine I built on.

  So I can now build on the 64-bit machine, but I'm getting a 64-bit program, which isn't what I want. This isn't an enormous program that needs more than 4GB of address space, and I'd like to be able to deploy it on 32-bit machines. I guess my only solution is to settle for 64-bit builds while I'm debugging on my 64-bit machine, and then rebuild a 32-bit version on my 32-bit machine when it's time to deploy. That's irritating, but I'm going to have to build a Mac version on my Mac, and a Linux version on my Linux machine, too, so it's just more of the same.

  A possible Solution:

  after readings tons of threads I found one explaining how to compile the actual OpenCV 3.8 a single lib (opencv_world.dylib).
  (Sorry I lost the link from which I got the idea.) Than I included this into my pro file. After this I did clean, than I had to repast the whole code into QTCreator.
  After this - and only then - the code got recognized correctly and the calcHist function was found.

  Thx to everybody for helping.

  Thanks for the answer.

  Starting the uninstaller.exe by double click from my program installation directory works fine. It removes all the file and my program is gone from the installed programs list. The main problem is that my users try to remove the program from the "Uninstall or change a program" menu (as we all do) and in that case it doesn't work (it shows the message above).

  UPDATE*** (In case others have similar problems)

  9 Months later I went on tackling this problem. Turns out it was the file wall. It was preventing QtCreator.exe and QMake.exe from calling the cmd.exe. That is why when I was running things manually it would appear like everything was working just fine, but as soon as I tried to use QtCreator it would not work. I was actually able to go into the windows event logs and see the blocking event from occurring.

  After getting those white listed everything seems to be working good now.

  So, finally, I got a solution (even 2 solutions):
  The trick is to pass the parameter as a real string list by using [ ] brackets.

  installer.executeDetached( "cmd", ["/C", "mkdir", "C:\\ProgramData\\My Company\\MyApp"], "C:\\ProgramData" );

  With this trick even the addOperation() function works fine:

  component.addOperation( "Execute", "cmd", ["/C", "mkdir", C:\\ProgramData\\My Company\\MyApp"] );

  I think this is closed.

  So, i got some updates on this issue.

  When using branches 5.12.0 OR 5.12.1, the issue is the one reported above.

  But if i use branch(or tag, i dunno) 5.12, and using the very same configure string command, i get the following error message when running the configure:

  ERROR: Feature 'opengles2' was enabled, but the pre-condition 'config.win32 || (!config.watchos && !features.opengl-desktop && libs.opengl_es2)' failed. ERROR: The OpenGL functionality tests failed! You might need to modify the include and library search paths by editing QMAKE_INCDIR_OPENGL[_ES2], QMAKE_LIBDIR_OPENGL[_ES2] and QMAKE_LIBS_OPENGL[_ES2] in the mkspec for your platform.

  Any thoughts?

  It's likely related to QTQAINFRA-1187. There's currently no mention of the macOS platform.

  You should comment there to get some more information.

  In between, one thing you can try, is to build only the QPA plugin from sources.

  I cannot copy from my work computer to my internet computer. If I can get Qt Designer working at home I will draw it up and paste in an image. That will be tonight's task at home, getting QT to run on my Windows box. I am using Centos Linux here at work. In the meantime:

  Imagine widget A with size 600 wide by 300 high. It has a set of radio buttons, push buttons, line edits, etc. When I set values in A it creates SIGNALS directed to SLOTS in B. A will need at least 10 controlling widgets. Example: A spin box or line edit in A can change the update rate of the strip chart, how fast it scrolls.

  Imagine widget B with the same size just below A. Each has a border and can be grabbed and moved with the mouse. B is where the strip chart graphics will be displayed, done in Open Gl. It has a pushbutton labeled "Hide A" that will cause widget A to be hidden. When pressed it changes its name to "Show A" which does the obvious.
  I am quite new at both Qt and OpenGL so maybe this question is more simple that it at first appears. Maybe not. I get to jump in on the deep end.

  @SGaist Well, I think no (if I understand your question right), because all paths to the compiler was setted right. Currently I'm trying to do a clean sysroot on my PC x86_64 (just a Qt+glib+gstreamer) with needed libraries (one question with pkg-config and Qt no resolved for me, yet) for the cross-compilation of target apps. As result I will produce a bash-script for a building an arm-sandbox to cross-compile from x86-64 machine to the ARM (specially imx6) and publish it here.

  Also thank you for your leading questions (because really currently available in the Ubuntu repos version of compiler is deprecated, I think)!

  It took a while, but I have now solved this problem so let me share the solution that I found. I did a combination of the following three things to made it work:

  I needed a single cdUp() for the deployment situation as opposed to the 3x cdUp() which is necessary when running from Qt Creator (as it is explained here http://doc.qt.io/archives/qt-4.8/qt-tools-plugandpaint-example.html but on http://doc.qt.io/archives/qt-4.8/deployment-mac.html it says to use only 1x cdUp()) I was lead to believe that the argument for QDir::cd() would be case insensitive on MacOS based on the referred documentation. Instead, I now used 'PlugIns' instead of 'plugins' to use the standard directory in the app bundle to store my plugins in. I did so because using cd in a Terminal also required using 'PlugIns' instead of 'plugins'. On the other hand, when running from QtCreator, it should be 'plugins' as that is the subdirectory that QtCreator creates when building. So, here is a second difference between running from QtCreator and when deploying I not only applied install_name_tool to my executable to fix the library references but I also applied it to my plugin libraries. I made sure to use @executable_path references only to my libdfmcore and also to the Qt framework libraries (so, no @rpath references as generated by a build from QtCreator or by macdeployqt)

  If you wish to inspect my solution in more detail, you can have a look at https://modeltech.org/download/dfm/dfm.macos.zip
