fileapi: no implicit compiler defines/includes from `CMAKE_<LANG>_COMPILE_OBJECT`
When a toolchain file defines
CMAKE_<LANG>_COMPILE_OBJECT with a command line that includes some implicit include directories and defines, these information are not available through the file API. This prevents IDEs from generating the correct intellisense information. Shouldn't this info be available to IDEs?
Also referring to another similar issue, #19514 The other issue talks in general about the availability of compiler information including implicit info. Will CMake include the info from command line as implicit info, as it already knows the compiler ID and can parse the command line?
