Re-trial of #7800. Deleting __WINESRC__
hacks.
JIRA issue: CORE-5743
- Add sdk/cmake/set_wine_module.cmake.
- Load set_wine_module.cmake at
top-level CMakeLists.txt.
- Use set_wine_module cmake function
and delete __WINESRC__ as possible.
- Delete many include_directories.
There is no need to compile our DLLs as shared libraries since we are
managing symbols exports and imports through spec files.
On my system, this reduces the configure-time by a factor of two.
