Hello all,

I have some compiler settings that require me to append headers after compile\_options in generated .rsp files. In current case, .rsp file → headers compiler\_options  
required case → compiler options headers  
is there a way to do it using target\_include\_directories() and target\_compile\_options()

```auto
add_library(lib STATIC src)
target_compile_options(lib PUBLIC options)
target_include_directories(lib AFTER PUBLIC headers)

```

Fine-grained flag ordering is not controllable in CMake today.

I suppose this has to do with the `.rsp` having include directives of its own that this needs to come afterwards? Would it be easier to add the flag to another `.rsp` file and use that through the options?
