Deprecated. Use the file(WRITE) command instead.

write_file(filename "message to write"... [APPEND])

The first argument is the file name, the rest of the arguments are messages to write. If the argument APPEND is specified, then the message will be appended.

NOTE 1: file(WRITE) and file(APPEND) do exactly the same as this one but add some more functionality.

NOTE 2: When using write_file the produced file cannot be used as an input to CMake (CONFIGURE_FILE, source file ...) because it will lead to an infinite loop. Use configure_file() if you want to generate input files to CMake.
