Is there a built-in way to write a string to a file (a la FILE(WRITE))

documentation that it does?)
Right now I am writing to a temporary file and running cmake -E
copy_if_different, then removing the temporary file, but this seems
inelegant and I am wondering if there is a better solution.
Not strictly "built-in", but it looks like the best way is:
set(CMAKE_CONFIGURABLE_FILE_CONTENT "${CONTENT}")
configure_file(
"${CMAKE_ROOT}/Modules/CMakeConfigurableFile.in"
"${PATH}" @ONLY
)
