I think so.  From your first sentence I assume your purpose is to
build software under Wine on Linux. If that assumption is correct,
then you don't need to worry about cross-compilation.  Instead, just
use the Windows version of CMake to help do the build.  I have done
that in the past, and in fact redundantly built a Windows version of
CMake that way as a proof of concept.  I also built and tested a fair
amount of other software that way including PLplot and a number of its
library dependencies and also ephcom2 (part of the timeephem project).
My purpose in these cases was to test the cross-platform capabilities
of my software projects.  That is, I made sure my software projects
built and tested without problems with MinGW (the Windows version of
gcc), MSYS (the Windows version of make and bash and other useful
tools), and the Windows version of CMake on a Windows platform (Wine
under Linux) just like my software project built and tested without
issues with Linux versions of gcc, make and bash, and CMake on the
Linux platform.
