Hello, Qt Development Team.

Recently, I tried to build the Qt6 Documentation from qt/qtbase
<https://github.com/qt/qtbase> sources. In order to
build Qt6 Documentation more conveniently, I prepared a
*CMakeUserPresets.json*
in the root directory with some required configurations introduced in:

    - Building Qt Documentation - Qt Wiki
    <https://wiki.qt.io/Building_Qt_Documentation#Building_Qt_6_Documentation>
    - Qt Build System Glossary - Qt Wiki
    <https://wiki.qt.io/Qt_Build_System_Glossary#Documentation-only_Build>

The following is the content of my *CMakeUserPresets.json*:

{
   "version": 4,
   "cmakeMinimumRequired": {
     "major": 3,
     "minor": 23,
     "patch": 0
   },
   "configurePresets": [
     {
       "name": "win32",
       "description": "Windows",
       "binaryDir": "${sourceDir}/build/${presetName}",
       "generator": "Ninja",
       "toolset": {
         "value": "v142,host=x64",
         "strategy": "external"
       },
       "architecture": {
         "value": "x64",
         "strategy": "external"
       },
       "cacheVariables": {
         "CMAKE_C_COMPILER": "cl.exe",
         "CMAKE_CXX_COMPILER": "cl.exe",
         "QT_HOST_PATH": "C:/Qt/6.3.2/msvc2019_64",
         "QT_NO_PACKAGE_VERSION_CHECK": true
       },
       "environment": {
         "LLVM_INSTALL_DIR": "C:\\Program Files\\LLVM"
       }
     }
   ]
}

The followings are the steps I used to build *docs_Core* target

    1. Run: *git clone https://github.com/qt/qtbase.git
    <https://github.com/qt/qtbase.git>*
    2. Run: *cd qtbase*
    3. Run: *git checkout 6.5*
    4. Add the above custom *CMakeUserPresets.json*
    5. Run: *vcvarsall.bat x64*
    6. Run: *cmake --preset win32*
    7. Run: *cmake --build build/win32 --target docs_Core*

However, it turns out that there is an error in the Step 7:

What happened? What did I miss? Can you help me to figure out this problem?

D:/Repo/GitHub/testing/qtbase/src/corelib/doc/qtcore.qdocconf:1: (qdoc) error: Cannot open file 'C:/Qt/Qt-6.5.3/./doc/global/qt-module-defaults.qdocconf': ??????????? Cannot open file 'C:/Qt/Qt-6.5.3/./doc/global/qt-module-defaults.qdocconf': ??????????? I don't use Windows so I am not sure how this can be fixed; it's looking for the .qdocconf file in the installation path rather than the source dir (in the git checkout).
