This does not seem to be valid, since Visual Studio complains that
it cannot open the project. I did not find anything in the
CMake documentation to set <TargetFramework> instead of <TargetFrameworkVersion>.
I also tried to go along with a "normal" TargetFrameworkVersion, "4.6.1".
If I do this, the generated project will target ".NET Framework 4.6.1" and I
cannot change the target framework to ".NET Standard 1.4" in Visual Studio via
the dropdown, as the option is not available. Visual Studio seems to be unable
to switch a project from .NET Framework to .NET Standard after it has been created.
Is it possible to generate a project targeting .NET Standard with CMake?
