          No problem, then when calling cmake you should set the generator to "MinGW Makefiles"

            Ok. make -G "MinGW Makefiles" c:\qca_2-1-0\ says

            CMake Error: Error: generator : MinGW Makefiles
            Does not match the generator used previously: NMake Makefiles Either remove the CMakeCache.txt file and CMakeFiles directory or choose a different binary directory.

            Should I remove the suggested file?

              Yes, you can empty the folder you used

                But this is the cmake folder c:\cmake.
                Do I only have to delete that file or can i specify a folder and how?

                  Don't call cmake from there.

                  Call it either in a build folder inside QCA's sources or at the same level as the sources

                    Ok I copied cmake into the qca folder and it said

                    C:\qca_2-1-0>cmake -G "MinGW Makefiles" c:\qca_2-1-0\

                    C:\qca_2-1-0>cmake -G "MinGW Makefiles" c:\qca_2-1-0

                    reedit the CMakeCache.txt

                    Then I copied QCA into a folder inside of the cmake folder and it says

                      Don't fiddle with these folders like that

                      @
                      cd C:\qca_2-1-0
                      mkdir build
                      cd build
                      C:\cmake\bin\cmake .. -G "MinGW Makefiles"
                      @

                      And it should start setting things up.

                          You are writing "Makefiles" wrong the f is not uppercased

                            Oh sorry :/
                            Now I get a new error. Inside the build folder there is a new file called CMakeCache.txt and a new folder called CMakeFiles in wich is also a new file called cmake.check_cache.

                              Are you using a self installed MinGW or the one provided with Qt ?

                                I'm not sure but I think I installed MinGW before or after Qt by myself for some reasons. In the Tools folder of Qt are the MinGW versions I mentioned before. So I installed it at least 2 times I guess.

                                Edit: I think c:\MinGW\ is the rest of an old installation. Because the folder has way less files than c:\Qt\Tools\mingw491_32\ or c:\Qt\Tools\mingw482_32\

                                  Then just remove it completely (however I don't remember if there's an entry for it in Windows Control Panel)

                                  IIRC, you should also have shortcut in Start Menu -> Qt that starts a command line with MinGW setup, use that one and you should be good to go.

                                    I can't find any hints how to uninstall it (if even possible) so I just renamed c:\MinGW to c:\MinGW_OLD just in case I need it for something I forgot.

                                    In Start Menu -> Qt are only these entries

                                      Ok then, take a look in your Qt folder and search for a file called qtenv2.bat

                                      Once you have found it you can create a shortcut containing:

                                      @C:\Windows\System32\cmd.exe /A /Q /K C:\Qt\Qt5.4.1\5.4.1\mingw49_32\bin\qtenv2.bat@

                                      Adapt the path to yours

                                      Then start the command line using that shortcut and you should have mingw at your disposition

                                        Ok, I did so. Thank you! When I run C:\qca_2-1-0\build>c:\cmake\bin\cmake .. -G "MinGW Makefiles" now, I'm getting the same error again.

                                          Did you start from a clean folder ?
