CMAKE_MESSAGE_INDENT — CMake 3.27.7 Documentation

# CMAKE_MESSAGE_INDENT

New in version 3.16.

The `message()` command joins the strings from this list and for log levels of `NOTICE` and below, it prepends the resultant string to each line of the message.

Example:

    list(APPEND listVar one two three)

    message(VERBOSE [[Collected items in the "listVar":]])
    list(APPEND CMAKE_MESSAGE_INDENT "  ")

    foreach(item IN LISTS listVar)
      message(VERBOSE ${item})
    endforeach()

    list(POP_BACK CMAKE_MESSAGE_INDENT)
    message(VERBOSE "No more indent")

Which results in the following output:

    -- Collected items in the "listVar":
    --   one
    --   two
    --   three
    -- No more indent
