qmlplugindump executable not found. It is required to generate the qmltypes file for VTK Qml

First, check the location of this error message ：

/.../VTKSource/GUISupport/QtQuick/qml/CMakeLists.txt

Open file , View associated snippets ：

# First, find the qmlplugindump executable

From here, we can see the execution process , It is through  qt_qmake_location find  qt_bin_dir , Again from qt_bin_dir In looking for  qmlplugindump This executable file . 

open Qt Installation directory , Search for qmlplugindump The executable of , Find the file here

/Users/.../Qt/5.15.2/clang_64/bin

Directly in CMakeList.txt Add a sentence , Code snippet after completion ：

# First, find the qmlplugindump executable
get_target_property(qt_qmake_location "Qt${vtk_qt_major_version}::qmake" LOCATION)
get_filename_component(qt_bin_dir "${qt_qmake_location}" PATH)
if (APPLE)
  get_filename_component(qt_bin_dir "${qt_bin_dir}" PATH)
endif ()
set( qt_bin_dir "/Users/allen/Soft/Qt/5.15.2/clang_64/bin/" )
find_program(QMLPLUGINDUMP_EXECUTABLE
  NAMES "qmlplugindump-qt${vtk_qt_major_version}" qmlplugindump

  message(FATAL_ERROR
    "qmlplugindump executable not found.\nIt is required to generate the "

endif ()
 

Then continue to configure -- generate -- make that will do .
