Visual Studio: Include all *.c and *.cpp by default

In Eclipse CDT, implementation files (*c., *.cpp) are included until you exclude them. In Visual Studio 2019, it is the reverse, i.e. files are excluded until you manually include them in your project. To include all files automatically and just exclude the file sim\ert_rtw\ert_main.c file, open your *.vcxproj file with an editor, remove all <CICompile Include = .../> lines and use the following:

<ItemGroup>
    <ClCompile Include="**\*.cpp" />
    <ClCompile Include="**\*.c" Exclude="sim\ert_rtw\ert_main.c" />
</ItemGroup>
