Is there a way to have colorized output in cmake for messages, (e.g. like here is written) , but only when output is not redirected to a file (and using only cmake's possibilities)? Because using that method, messages in the file are colorized too (escape sequences printed).

I'd like to be able to force and compiler flags like -fdiagnostics-color for gcc or -fcolor-diagnostics for clang. On some platforms compiler doesn't colorize output without these flags. I think it's impossible to do this correctly. The flags are cached and every time, when make is started, it uses the same value as was configured when cmake was started for first time. I don't know how to change flags in dependence if output is redirected to screen or to file, but if it is possible, I'd like to know.

For the other question, with recent enough versions of clang or gcc I get automatic coloring depending on whether the output is a terminal. I'm sorry if you can't upgrade your compiler right now, but I'm sure you'll do it eventually :)
