* [yaml-cpp] Update to 0.8.0.
- The config path has changed to `lib/cmake/yaml-cpp`.
- pkg-config files are installed to `lib/pkgconfig`.
- dll.h uses a new variable for control and should be patched outside
of Windows.
* [yaml-cpp] Backport CMake fixes from upstream.
The patch is a shortened version from:
https://github.com/jbeder/yaml-cpp/pull/1212
It fixes issues with downstream projects using the old target, and makes
the CMake config more easily relocatable.
The patch was rebased on the 0.8.0 release, and the CI and tests bits
were omitted.
* [yaml-cpp] Update baseline.
