+CMP0027
+-------
+
+Conditionally linked imported targets with missing include directories.
+
+CMake 2.8.11 introduced introduced the concept of
+INTERFACE_INCLUDE_DIRECTORIES, and a check at cmake time that the
+entries in the INTERFACE_INCLUDE_DIRECTORIES of an IMPORTED target
+actually exist. CMake 2.8.11 also introduced generator expression
+support in the target_link_libraries command. However, if an imported
+target is linked as a result of a generator expression evaluation, the
+entries in the INTERFACE_INCLUDE_DIRECTORIES of that target were not
+checked for existence as they should be.
+
+The OLD behavior of this policy is to report a warning if an entry in
+the INTERFACE_INCLUDE_DIRECTORIES of a generator-expression
+conditionally linked IMPORTED target does not exist.
+
+The NEW behavior of this policy is to report an error if an entry in
+the INTERFACE_INCLUDE_DIRECTORIES of a generator-expression
+conditionally linked IMPORTED target does not exist.
+
+This policy was introduced in CMake version 3.0. 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.
