This might be fixed now.

Then you should add a define for WSMP_FUNC according to the name 
mangling scheme that your Wsmp library uses.
That is, if you don't have Wsmp, don't try to build ClpCholeskyWssmp.cpp.

The main supported buildsystem for CoinUtils, Clp, Cbc, etc is the 
autotools-based system, which should work with MS compilers under MSys2 
on Windows, too.
This buildsystem has been updated in the master branches, that is, the 
current development versions of CoinUtils, Clp, Cbc, etc., recently, 
which also brought some changes to the code itself. This very likely 
broke these MSVS project files. Noone looked into fixing these so far.
