Hello,
recently I realized that most pre-defined CMake variables are not
available in scripting context. In my use case I had to identify a Linux
host system. Unfortunately only CMAKE_HOST_{APPLE,SOLARIS,UNIX,WIN32}
are available in scripting context.
I wondered if all supported host operating systems support the uname(3)
function call? If yes we could also make CMAKE_HOST_SYSTEM_NAME in
scripting context.
A proof-of-concept patch is located here:

Thanks,
Gregor
