      I downloaded qt-everywhere-src-5.15.0, and compiled successfully. but it doesn't include 'qtchats' by default.
      when I try to compile qtcharts, some error occur.
      I use x86 Native Tools Command Prompt for VS 2019, and commands are below:

      mkdir build_chart
      cd build_chart
      c:\Qt\Qt-5.15.0\bin\qmake.exe d:\Qt\qt-everywhere-src-5.15.0\qtcharts
      nmake
      errors are:

      I am confused about the error as 'Q_DECLARE_PUBLIC' is defined in qglobal.h and many submodules use this MACRO, why only qtchart has error in calling this MACRO.
      How to fix this error, can anyone help, thanks.
