Error at Flex section of "win_flex_bison_custom_build.props" file

[Hynek]

There should be: <OutputFile>%(Filename).flex.cpp</OutputFile>
instead of: <OutputFile>%(Filename).tab.cpp</OutputFile>

at the Flex section. This is a corrected one:

  <ItemDefinitionGroup>
    <Flex>
      <OutputFile>%(Filename).flex.cpp</OutputFile>
      <Wincompat>true</Wincompat>
      <CommandLineTemplate>
start /B /WAIT /D "%(RootDir)%(Directory)" win_flex.exe [AllOptions] "%(Filename)%(Extension)"
exit /b %errorlevel%</CommandLineTemplate>
      <Outputs>%(RootDir)%(Directory)%(OutputFile);</Outputs>
      <ExecutionDescription>Process "%(Filename)%(Extension)" flex file</ExecutionDescription>
    </Flex>
  </ItemDefinitionGroup>

Thank you!
There is a typo in win_flex_bison_custom_build.props file. I've fixed it and updated packages.
