Hello,
I’ve been struggling to include VTK into QML. I have installed VTK 9.3 through ninja, following the Kitware’s gitlab [docs](https://gitlab.kitware.com/vtk/vtk/-/blob/master/Documentation/docs/build_instructions/build.md). I also have set env variables `QML_IMPORT_PATH` and `QML_IMPORT_PATH` to `VTKInstallation/lib/qml/vtk-9.3`. Everything seems to be working, **except QTCreator not identifying VTK qml Components**
Here is my CmakeLists.txt:
```cmake
cmake_minimum_required(VERSION 3.16)
project(hii VERSION 0.1 LANGUAGES CXX)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
find_package(Qt6 6.5 REQUIRED COMPONENTS Quick OpenGL)
find_package(VTK REQUIRED)
include(${VTK_USE_FILE})
qt_standard_project_setup(REQUIRES 6.5)
qt_add_executable(apphii
main.cpp
)
qt_add_qml_module(apphii
URI hii
VERSION 1.0
QML_FILES
Main.qml
)
set_target_properties(apphii PROPERTIES
WIN32_EXECUTABLE TRUE
)
target_link_libraries(apphii
PRIVATE Qt6::Quick
${QT_LIBRARIES}
${OPENGL_LIBRARIES}
${VTK_LIBRARIES}
)
include(GNUInstallDirs)
install(TARGETS apphii
BUNDLE DESTINATION .
LIBRARY DESTINATION ${CMAKE_INSTALL_LIBDIR}
RUNTIME DESTINATION ${CMAKE_INSTALL_BINDIR}
)
```
Now, my `Main.qml` contains these VTK lines:
```qml
import VTK 9.3 # imports just fine!
...
VTKRenderWindow { # Unknown Component (M300)
id: vtkwindow
width: 400
height: 400
}
```
The code runs without any problems, nonetheless the qtcreator doesn’t seem to recognize the module’s components.
BTW, the directory `VTKInstallation/lib/qml/vtk-9.3` contains `qmldir` and `plugins.qmltypes`:
`qmldir` file:
```auto
import QtQuick.tooling 1.2
// This file describes the plugin-supplied types contained in the library.
// It is used for QML tooling purposes only.
//
// This file was auto-generated by:

```

}
```
Would someone please why QTCreator doesn’t know about the components?
Thank you very much in advance

Hello,
Please, you can try taking a look at this: [Issue: Qt Creator can’t find custom C++ QtQuick Components, but compilation still works | Qt Forum](https://forum.qt.io/topic/121079/issue-qt-creator-can-t-find-custom-c-qtquick-components-but-compilation-still-works) and this: [qt - How do I import components into QtQuickDesigner? - Stack Overflow](https://stackoverflow.com/questions/69187321/how-do-i-import-components-into-qtquickdesigner).
best,
