Build issues with CMake on Windows

[pet-mit]

Hello,
We are having build issues for v9.12 on Windows (Release config). During the install step (copied from here), we receive the following error:
LINK : fatal error LNK1189: library limit of 65535 objects exceeded

Would you have an idea of what's wrong?
(FYI, there is no issue with v9.11)

Thank you for your help,
Peter

PS : when in Debug config, the same error happens during the build step

yes, This is a new issue since we migrate to shared library to avoid ODR violation inside protobuf.
Currently I don't know how to fix it.

One possible solution is to split the full lib into multiple smaller libraries then link those into the final executable (full_lib1.lib, full_lib2.lib, etc.). I don't know how inconvenient that would be for consumers of that library.

But it kind of misses the point of combining ortools.lib absl_*.lib zlib*.lib re2.lib *protobuf*.lib Cbc*.lib Cgl.lib Clp*.lib Osi*.lib CoinUtils.lib libscip.lib into ortools_full.lib.

In the end, consumers might as well use the libs above instead of the full_lib.

since we migrate to ortools.dll their is no more ortools_full.lib generated nor <deps>.lib (they should be <deps>.dll too)

cmake: remove ortools_full.lib generation on windows
