[CMake] Help cmake to resolve link lines with multiple circulardependencies?

[Alexandre.Feblot at thomsonreuters.com]

Eric,

in fact we build static libraries.
And we currently use a custom build system with a "handmade" link line.

Don't know how to do that but I did face some similar issue which I
didn't manage
to solve using CMake.
I was able to solve it on unix somehow easily but not on Windows because
of the dll_import/export thing.

Thus I'm pretty curious,

Do you currently compile your code on Windows using shared lib?
If yes how do you compile your code with your current build system?
