            What exactly did you do ?
            What was the outcome ?

            Did you follow the documentation provided by the project itself ?

            You seem to have already checked it based on one of your previous answer. However you did not explain what your issue was with them.

              If I execute files below thay just do nothing

              Download the latest SW (Software Network https://software-network.org/) client from https://software-network.org/client/.
              Run sw setup (may require administrator access)
              Run sw build org.sw.demo.google.tesseract.tesseract-master.

                As I said earlier, you show no signs of having any tesseract .h files at all?

                I don't think you are reading and following all the instructions. Please do so. For example, in https://tesseract-ocr.github.io/tessdoc/Compiling.html#windows

                Checkout tesseract sources git clone https://github.com/tesseract-ocr/tesseract tesseract && cd tesseract.

                I can see that would at least give you tesseract/include/tesseract/*.h, which is what you need.....

                    I give up. You are not listening and not following the instructions. Just expecting people here who know nothing about tesseract to solve it for you.

                    I can not run these files

                    These are not files to run.

                          How can i check what do I actually have?

                          Msys2

                          Mingw-w64

                          Looking for command as below, to find what do I actually have
                          C:\Qt\Tools\mingw900_64>gcc -dumpversion
                          11.2.0

                            The Qt installer provides MinGW directly. It has nothing to do with MSys.

                              So my next step must be here
                              Mingw-w64

                              Mingw-w64 allows building 32- or 64-bit executables for Windows. It can be used for native compilations on Windows, but also for cross compilations on Linux (which are easier and faster than native compilations). Most large Linux distributions already contain packages with the tools need for a cross build. Before building Tesseract, it is necessary to build some prerequisites.

                              For Debian and similar distributions (e. g. Ubuntu), the cross tools can be installed like that:

                              Development environment targeting 32- and 64-bit Windows (required)

                              apt-get install mingw-w64

                              Development tools for 32- and 64-bit Windows (optional)

                              apt-get install mingw-w64-tools

                              These prerequisites will be needed:

                              libpng, libtiff, zlib (binaries for Mingw-w64 available as part of the GTK+ bundles)
                              libicu
                              liblcms2
                              openjpeg
                              leptonica
                              

                              what should i exactly do?

                                Why are you following the cross-compilation instructions from Linux to Windows ?

                                  Is there the similar command line in MinGW that supplied by QT?

                                    If memory serves well, you should have some shortcuts in the start menu that starts a command line instance that is ready to use with MinGW.
