Forbidding find_package() to search for some packages in Windows' reg…

…istry

On Windows, when configuring "glog" or "gflags", a path to <package>-config.cmake is stored
under the form of a registry key (HKEY_CURRENT_USER\Software\Kitware\CMake\Packages\<PackageName>).
A a consequence, when deploying/installing another version of antares-deps, supposed to be
completely independent, an already compiled package ("glog" or "gflags") is found by the
find_package(<PackageName>) in the Windows registry.
As we can't make packages "glog" or "gflags" not to store paths in the Windows' registry,
we tell find_package(<PackageName>) not to search in registry, by using NO_CMAKE_PACKAGE_REGISTRY option.
