[cmake-developers] CMake removes /DEF: option in CMAKE_SHARED_LINKER_FLAGS

[Alexander]

In some cases it is not convenient to program something in CMakeFile.txt
(for example when I clone some 3rd party project and want to change its
build procedure).
Thus the possibility to add additional .defs files with the help of *command
line* options would be very nice. Such a command line option exists:
-DMAKE_SHARED_LINKER_FLAGS, but it deliberately ignores /DEF: which makes
impossible to add /DEF: this easy (and for me preferable) way.

I would like to get an answer from CMake developers, if it is an expected
behavior of  MAKE_SHARED_LINKER_FLAGS.
If yes: what is the logic behind it and why this special handling of
MAKE_SHARED_LINKER_FLAGS is not documented on
https://cmake.org/cmake/help/v3.15/variable/CMAKE_SHARED_LINKER_FLAGS.html.
If no: issue a bug.
