Deprecated. Use the :command:
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: :command:
file(WRITE) and :command:
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 :command:
configure_file if you want to
generate input files to CMake.
