Qt creator can not parse cmake version after update from Qt 6.5.3 to Qt 6.7.2

[Roget.P]

this issue has stocked to me for 2 days, I really want to fix this.

Backgound

I recently update Qt 6.5.3 to Qt 6.7.2 for Windows 10, there is a issue "error: The kit needs to define a CMake tool to parse this project." when I opened a project. Then I checked Edit>Preference>Kits, I see a warning says Cmake is unconfigured.

and I check Cmake Setting, It says cmake version is not parseable.

And there is no Cmake generator

What have I done

I tried to remove all components of Qt and install all over again using Qt maintenance tool, but nothing changes, I tried to install Qt creator Community 13.0.2 and Qt Creator 14.0.0-beta2 Community but nothing changes, I tried to Install Qt 6.5.3, Qt 6.6.3 and Qt 6.7.2 but nothing changes.

I checked my enviromment path, I think everything is fine.

Qt672 meas kits path for Qt 6.7.2, I alse have QT663 and qt653 for each specific version of Qt kit.

What is bizzared

I use Qt design studio for fun and I checked its preference setting, I found Qt design studio can parse Cmake version!!!!

And this show what I installed

This is so frustrating and sucks! I search every related web page, asked ChatGPT mang questions, But I really can not find a solution.

Any suggestion will be appreciated, Please help me!

can't be solved, I just use virtual machine to install Qt all over agagin

I would suggest starting the Maintainance Tool and reinstall the CMake version (first remove, restart, and add again).

Qt Creator gets the Qt SDK CMake information from C:\Qt\Tools\sdktool\share\qtcreator\QtProject\qtcreator\cmaketools.xml. Have a look in the xml file and check for sanity.

Here is my version:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE QtCreatorCmaketools>
<!-- Written by sdktool , 2024-07-12T09:30:39. -->
<qtcreator>
 <data>
  <variable>CMakeTools.0</variable>
  <valuemap type="QVariantMap">
   <value type="bool" key="Autodetect">true</value>
   <value type="QString" key="Binary">C:/Qt\Tools\CMake_64\bin\cmake.exe</value>
   <value type="QString" key="DisplayName">CMake 3.29.3 (Qt)</value>
   <value type="QString" key="Id">qt.tools.cmake</value>
  </valuemap>
 </data>
 <data>
  <variable>CMakeTools.Count</variable>
  <value type="int">1</value>
 </data>
 <data>
  <variable>Version</variable>
  <value type="int">1</value>
 </data>
</qtcreator>

Qt Creator uses sdktool/share/qtcreator/QtProject/qtcreator/cmaketools.xml as a template for it's own settings.

Go to "%appdata%\QtProject\qtcreator\cmaketools.xml" and again check for sanity.

My version looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE QtCreatorCMakeTools>
<!-- Written by QtCreator 13.0.2, 2024-07-12T09:40:59. -->

Here is the Qt Creator's function that checks for validity:

bool CMakeTool::isValid() const
{
    if (!m_id.isValid() || !m_introspection)
        return false;

    if (!m_introspection->m_didAttemptToRun)
        readInformation();

    return m_introspection->m_haveCapabilitites && !m_introspection->m_fileApis.isEmpty();
}

It can fail if <value type="QString" key="Id">qt.tools.cmake</value> is empty, Id that is.

Or if C:\Qt\Tools\CMake_64\bin\cmake.exe -E capabilities fails to run.

Which case do you have?

In order to find out if Qt Creator for some reason has some borked settings in "%appdata%\QtProject\qtcreator you can start:

$ C:\Qt\Tools\QtCreator\bin\qtcreator.exe -temporarycleansettings
