Modern way to set compiler flags in cross-platform cmake project

Question

I want to write a cmake file that sets different compiler options for clang++, g++ and MSVC in debug and release builds. What I\'m doing currently looks something like this:

Answer 1

Another way is to use .rsp files.

set(rsp_file "${CMAKE_CURRENT_BINARY_DIR}/my.rsp")
configure_file(my.rsp.in ${rsp_file} @ONLY)
target_compile_options(mytarget PUBLIC "@${rsp_file}")

which might make the inclusion of multiple and esoteric options easier to manage.
