6856567eda Rework CMakeLists.txt 
Dependencies:
- Add dependencies as subprojects instead of prebuild (aka imported target)
- add zlib project
- Use Cbc as CMake subproject instead of prebuilt
- Add log between each subproject
- Force gflags namespace to gflags

Or-tools:
- Rework python.cmake support
- Fix missing ortool.util in python (#558)
- Try to use static library for ortools::proto
pros: can use target_link_libraries to get includes etc...
cons: lot of symbols undefined since libortools.so will strip everything -_-
- Use add_library(XXX OBJECT) for ortools/*
- fix get version from git when using small depth copy
- Create Install rule for ortools
- Don't create export rules
note: since we use subprojects instead of Imported Target,
ortools export complained against target deps "that is not in the export set."

Update windows support
- add swig project
- Protobuf force the use of /MD instead of /MT
- or-tools use /MD by default
- Add missing ws2_32
- Add missing psapi
- Update windows disable warnings list
- Build Static or-tools on Windows
- fix windows export symbols leak issue
