[CMake] Parellel Visual Studio builds of targets in the same CMakeLists.txt sometimes fail

[Robert Dailey]

Are you on Windows Vista or higher? If so, have you tried running
Visual Studio as Administrator and doing a build? I don't have this
problem, but my first thought was that maybe you are having some
permissions errors. I also have several targets that build in parallel
in the same directory.
