CMake Warning at CMakeLists.txt:9 (message):
In 1.11 releases, we are releasing experimental alternative building
mode.By setting -DLEGACY_MODE=OFF you can test our advances in modern CMake
building and provide early feedback. The legacy support is set by default
in 1.11, when you complete build updating scripts please update the build
flags as mentioned in README.md and set -DLEGACY_BUILD=OFF. The legacy
support will be removed at 1.12.0 release.

CMake Deprecation Warning at CMakeLists.txt:17 (cmake_policy):
The OLD behavior for policy CMP0077 will be removed from a future version
of CMake.

The cmake-policies(7) manual explains that the OLD behaviors of all
policies are deprecated and that a policy should be set to OLD only under
specific short-term circumstances. Projects should be ported to the NEW
behavior and not rely on setting a policy to OLD.
