[CMake] Alternative to `add_compile_options` in Toolchain Files

[Jayesh Badwaik]

Hi,

In https://gitlab.kitware.com/cmake/cmake/issues/19074, it was mentioned that 
instead of `add_compile_options`, `CMAKE_CXX_FLAGS_INIT` should be used. An 
issue with this is that `CMAKE_CXX_FLAGS_INIT` flags are propogated to the 
linker as well, wherein, the linker warns about `[-Wunused-command-line-
argument]` if those warnings are enabled. 

Is there an alternative to `CMAKE_CXX_FLAGS_INIT` which avoids these issues? 

Thanks
