      I am trying to compile a github project for Qt, using CMake. Here is the settings:

      034c46ba-3dfb-47e5-a5b0-6c9a24c2014a-image.png ![alt text](image url)

      But I cannot setup a correct QT path: Qt5_DIR-NOTFOUND

      Here is the outcome message:

      CMake Error at CMakeLists.txt:32 (find_package):
        By not providing "FindQt5.cmake" in CMAKE_MODULE_PATH this project has
        asked CMake to find a package configuration file provided by "Qt5", but
        CMake did not find one.
      
        Could not find a package configuration file provided by "Qt5" with any of
        the following names:
      
          Qt5Config.cmake
          qt5-config.cmake
      
        Add the installation prefix of "Qt5" to CMAKE_PREFIX_PATH or set "Qt5_DIR"
        to a directory containing one of the above files.  If "Qt5" provides a
        separate development package or SDK, be sure it has been installed.
      

      I even setup Qt in PATH:

      1230d7db-242d-4457-ad56-811a3578602d-image.png

      I always got Qt5_DIR-NOTFOUND as feedback. What should I do in order to overcome this error ?

        Hi,

        The PATH environment variable won't help there.

        @Flaviu-0 said in Qt5_DIR-NOTFOUND:

        Add the installation prefix of "Qt5" to CMAKE_PREFIX_PATH

        Define it to point to your Qt 5 installation as suggested when calling cmake.

        Or if you also have Qt Creator, just build it using it.

          Yes, I have used Qt Creator to compile with CMake, specifically, I have loaded CMakeLists.tzt into Qt Creator, but there I have another troubles:

          Run Build Command(s):C:/Project/ninja-win/ninja.exe cmTC_df434 && [1/2] Building C object CMakeFiles\cmTC_df434.dir\testCCompiler.c.obj
              [2/2] Linking C executable cmTC_df434.exe

              RC Pass 1: command "rc /fo CMakeFiles\cmTC_df434.dir/manifest.res CMakeFiles\cmTC_df434.dir/manifest.rc" failed (exit code 0) with the following output:
              The system cannot find the file specified
              ninja: build stopped: subcommand failed.
          

          I guess the CMake way it is the easy one.

            Your build started correctly.

            Qt Creator uses cmake since it's a cmake project. The main difference is that the paths for Qt are pre-configured so you do not have to worry about that.

            What is failing here is the rc call. How does your CMakeFile.txt look like ?

              In fact, is about this CMakeLists.txt: https://github.com/cnr-isti-vclab/meshlab/blob/master/src/CMakeLists.txt

                  It's the rc part that fails. Did you a fresh build from start ?

                    @SGaist Thank you a lot. I have succeeded into compiling that project, using CMake and VS2017.

                        I have generated VS2017 solution file using CMake, but I get out Qt option, so I am not using Qt right now, just VS2017. Now, I can compile, run and debug reliable this project. Thank you a lot for your support.

                          And another information for those who have the same issue, I noticed that CMake chooses Qt5_DIR with this values:

                          b3287b72-9ec4-482f-a89b-50e4384d1235-image.png C:/Qt/Qt5.12.10/5.12.10/msvc2017_64/lib/cmake/Qt5

                          Hope it helps.
