Thank you very much, Brad. I found that WINDOWS_EXPORT_ALL_SYMBOLS was set
in my CMakeLists.txt.
After I removed it the /DEF parameter from CMAKE_SHARED_LINKER_FLAGS
appeared in the linking command.

That behavior is not default, but
I am sorry that I did not make it clear from the beginning. You are right.
Not only MSBuild, but MSVC linker (link.exe) accepts only one /DEF
parameter according to

This was the first you've mentioned using more than one copy of the flag.
I tested with this:
```
string(APPEND CMAKE_SHARED_LINKER_FLAGS "
Well, I have tested this proposal as well and I can confirm that it does
not work for me. I have added this code to my CMakeLists.txt:
string(APPEND CMAKE_SHARED_LINKER_FLAGS " -DEF:\"foo_1.def\"
-DEF111:\"foo_1.def\"")
string(APPEND CMAKE_CXX_STANDARD_LIBRARIES " -DEF:\"foo_2.def\"") # just in

The code
```
string(APPEND CMAKE_SHARED_LINKER_FLAGS "
-DEF:\"${CMAKE_CURRENT_SOURCE_DIR}/foo.def\"")
```
works fine for me.
So does this:
```
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

A module definition file can be passed as a normal source file and
CMake will automatically add `/DEF:...` to the link
