Configuring, I got error.

//error log

CMake Error at C:/Qt/5.6/msvc2013_64/lib/cmake/Qt5DataVisualization/Qt5DataVisualizationConfig.cmake:15 (message):
  The imported target "Qt5::DataVisualization" references the file

     "C:/Qt/5.6/msvc2013_64/bin/Qt5DataVisualization.dll"

  but this file does not exist.  Possible reasons include:

  * The file was deleted, renamed, or moved to another location.

  * An install or uninstall procedure did not complete successfully.

  * The installation package was faulty and contained

     "C:/Qt/5.6/msvc2013_64/lib/cmake/Qt5DataVisualization/Qt5DataVisualizationConfig.cmake"

  but not all the files it references.

Call Stack (most recent call first):

  source/qmlsurface/CMakeLists.txt:28 (FIND_PACKAGE)

However, bin/lib folder have "DataVisualization.dll/lib" file instead of "Qt5DataVisualization.dll/lib". Is there any reason ?

Do you have a commericial license? The DataVisualization module was only added to the open source license (GPL) in Qt 5.7. Also, how did you install Qt? Using the online installer/maintenance tool, the examples are in sub-directories by version (e.g., C:/Qt/Examples/Qt-5.6), but yours doesn't not seem to use the versioned sub-directories structure.
