Qt 6 Cmake Error and totally lost on a solution
So I have an application I have been working on for a month in Qt 6 compiling with msvc2019 x64. So I had a problem earlier today (can't even remember what it was) so I updated visual studio and everything went crazy. FYI it is a gui application, anyway I finally wound up uninstalling and reinstalling qt. So I now have the latest version of both as of today. So here is the output when I try to build:
Running C:\Qt\Tools\CMake_64\bin\cmake.exe -S "C:/Users/Stacey Tower/Desktop/DitaTransform/DXT" -B "C:/Users/Stacey Tower/AppData/Local/Temp/QtCreator-ePlksq/qtc-cmake-VRacWRIm" -GNinja "-DCMAKE_BUILD_TYPE:String=Debug" "-DQT_QMAKE_EXECUTABLE:STRING=C:/Qt/6.0.1/msvc2019_64/bin/qmake.exe" "-DCMAKE_PREFIX_PATH:STRING=C:/Qt/6.0.1/msvc2019_64" "-DCMAKE_C_COMPILER:STRING=C:/Qt6/Tools/QtCreator/bin/clang/bin/clang-cl.exe" "-DCMAKE_CXX_COMPILER:STRING=C:/Qt6/Tools/QtCreator/bin/clang/bin/clang-cl.exe" in C:\Users\Stacey Tower\AppData\Local\Temp\QtCreator-ePlksq\qtc-cmake-VRacWRIm.
-- The CXX compiler identification is unknown

Tell CMake where to find the compiler by setting either the environment
variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path
to the compiler, or to the compiler name if it is in the PATH.

You will notice that at the top of the output some of the references are to C:/Qt which is my new install directory and some are still to C:/Qt6 which was the old install directory that I uninstalled before I installed the new version. I have changed every path, gone into the registry and gotten rid of every reference to c:/Qt6 I could find and I have no Idea what to do next. The only way I can get even a blank application to build is to go into the cache file entry in appdata and changing the two references of c:/Qt6 to c:/Qt and it builds once. Anyone Please Help!!!!!
I can't get a capture of it but in my kit I also have a warning that says Warning! Cmake has a path to a c++ compiler set even though the kit has no valid toolchain.
Any help would be greatly appreciated...Thanks
I don't think this is proper compiler. This one is used by QtCreator for code model, not to build projects.
It looks like you installed Qt for msvc2019_64, so you need Microsoft compiler. Did you install Visual Studio or MS build tools?
@jsulm I installed Visual Studio
@shathcock Actually I didn't install visual studio just ran the updates for the 2019 version
@shathcock That worked !!!! Thank you very very much. I changed the compilers to 14.xxxx x64 and it's working now!
