[CMake] Generating stand-alone Visual Studio projects?

[Petr Kmoch]

Hi Magnus.

I am afraid that's not really possible (safely). CMake uses absolute paths
all over the place (by design), so all output file paths etc. are hardcoded
in the .sln and .vc[x]proj files to the paths applicable where they were
generated. You can experiment with the variable CMAKE_USE_RELATIVE_PATHS,
but even its documentation warns that it's unreliable.
