RFE Provide "User defined options" summary for options set in the native file

[evelikov]

Describe the bug

Currently meson produces very nice summary when user has defined any options on the command line. Although it does not list any options that have been set via a native file.

To Reproduce

Grab any meson project and add the following native file:

$ cat native.ini
[project options]
strip = true

Then setup as normal and observe the output:

$ meson setup build/
...
  User defined options
    Native files     : native.ini // only the file and not the options within

Expected behavior

Print the option from the native file, unless overridden. Eg:

$ meson setup build/
 ...
  User defined options
    Native files     : native.ini
        +> strip: true // better visualisation ideas highly appreciated

$ meson setup -D strip=false build/
 ...
  User defined options
    Native files     : native.ini
    // should probably mention that strip is set, but overridden?
    strip            : false
