+Plain and keyword target_link_libraries signatures cannot be mixed.
+
+CMake 2.8.12 introduced the target_link_libraries signature using the
+PUBLIC, PRIVATE, and INTERFACE keywords to generalize the LINK_PUBLIC
+and LINK_PRIVATE keywords introduced in CMake 2.8.7.  Use of
+signatures with any of these keywords sets the link interface of a
+target explicitly, even if empty.  This produces confusing behavior
+when used in combination with the historical behavior of the plain
+target_link_libraries signature.  For example, consider the code:
+
+::
+
+ target_link_libraries(mylib A)
+ target_link_libraries(mylib PRIVATE B)
+
+After the first line the link interface has not been set explicitly so
+CMake would use the link implementation, A, as the link interface.
+However, the second line sets the link interface to empty.  In order
+to avoid this subtle behavior CMake now prefers to disallow mixing the
+plain and keyword signatures of target_link_libraries for a single
+target.
+
+The OLD behavior for this policy is to allow keyword and plain
+target_link_libraries signatures to be mixed.  The NEW behavior for
+this policy is to not to allow mixing of the keyword and plain
+signatures.
+
+This policy was introduced in CMake version 2.8.12.  CMake version
+|release| warns when the policy is not set and uses OLD behavior.  Use
+the cmake_policy command to set it to OLD or NEW explicitly.
