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 3.0.0. 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.
