cmake: tidy up passing compiler and linker options

Browse Source 
- prefer `set_property()` over `target_compile_options()`, to use
  the modern style.

  Follow-up to 8017592163 #939

- prefer to append to compiler/linker options in examples/tests.
  To prevent accidentally overriding a previously set option.

  Follow-up to 14a709a72f #1686
  Follow-up to 854cfa8292 #1524

- replace `LINK_FLAGS` with `LINK_OPTIONS` that superceded it, for
  CMake 3.13+.

  Follow-up to 854cfa8292 #1524
  https://cmake.org/cmake/help/v4.1/prop_tgt/LINK_OPTIONS.html

Closes #1690
