Install PySide6 failed due to QT not found in macos.

Hello,

When I follow the pyside6 installation guide as below page, error happens in building/installation.
https://doc.qt.io/qtforpython/gettingstarted-macOS.html

bash-3.2$ python3 setup.py build --qtpaths=/Users/bean/Qt/6.4.0/macos/bin/qtpaths --build-tests --ignore-git --parallel=8 --qt-target-path=/Users/bean/Qt/6.4.0/
In directory /Users/bean/work/pyana/pyside/pyside-setup:
	Running command:  /Library/Developer/CommandLineTools/usr/bin/python3 setup.py build --qtpaths=/Users/bean/Qt/6.4.0/macos/bin/qtpaths --build-tests --ignore-git --parallel=8 --qt-target-path=/Users/bean/Qt/6.4.0/ --internal-build-type=shiboken6
running build

Could not find Qt via provided option --qt-target-path=/Users/bean/Qt/6.4.0/ Error was:

.....

RuntimeError: 
Failed to configure CMake project: '/Users/bean/work/pyana/pyside/pyside-setup/sources/shiboken6/config.tests/target_qt_mkspec'
Configure args were:

Return code: 1

Since I have install QT package and gave the directory path to qt-target-path, the error message still report could not find QT. (I have tried /Users/bean/Qt/, /Users/bean/Qt/6.4.0/macos)
Also, the path of qtpaths are given as /Users/bean/Qt/6.4.0/macos/bin/qtpaths

Do anyone know how can I fix the installation?

Thanks

Hello,

I found the reason why PySide6 installation failed.
Here is another error message

RuntimeError: 
Failed to configure CMake project: '/Users/bean/work/pyana/pyside/pyside-setup/sources/shiboken6/config.tests/target_qt_info'
Configure args were:
    /opt/homebrew/bin/cmake -G Ninja -S /Users/bean/work/pyana/pyside/pyside-setup/sources/shiboken6/config.tests/target_qt_info -B /Users/bean/work/pyana/pyside/pyside-setup/build/config.tests/target_qt_info_twe5ehbb -DQFP_QT_TARGET_PATH=/Users/bean/Qt/6.4.0/
Return code: 1

with error:
    CMake Error: CMake was unable to find a build program corresponding to "Ninja".  CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build tool.
    CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
CMakeOutput.log:
    The system is: Darwin - 21.6.0 - arm64

After I install "Ninja" with homebrew, the installation success.
So, that's nothing about QT path.....

Just omit the --qt-target-path= option. It is for cross-builds only. qtpaths should be sufficient, or, better, have that version of Qt in PATH.
