Dear all, A naive grep tells me the IAR compiler detection sets CMAKE_CXX_LINK_FLAGS in its compiler detection.
If I use `CMAKE_CXX_LINK_FLAGS`, I have to pass the option manually, which is not convenient. I was looking for something more automatic: 1. I set `cxx_std_14` in `target_compile_feature` of my `CMakeLists.txt`; 2. Then `CMAKE_CXX14_STANDARD_COMPILE_OPTION` is added to the compiler flags (which is the case); 3. Then `CMAKE_CXX14_STANDARD_LINK_OPTION` (or `CMAKE_CXX14_STANDARD_COMPILE_OPTION` by default) is added to the linker flags. I cannot find in the documentation if such a thing is possible. Is it?
