CMP0041 ------- Error on relative include with generator expression. Diagnostics in CMake 2.8.12 and lower silently ignored an entry in the :prop_tgt:`INTERFACE_INCLUDE_DIRECTORIES` of a target if it contained a generator expression at any position. The path entries in that target property should not be relative. High-level API should ensure that by adding either a source directory or a install directory prefix, as appropriate. As an additional diagnostic, the :prop_tgt:`INTERFACE_INCLUDE_DIRECTORIES` generated on an :prop_tgt:`IMPORTED` target for the install location should not contain paths in the source directory or the build directory. The ``OLD`` behavior for this policy is to ignore relative path entries if they contain a generator expression. The ``NEW`` behavior for this policy is to report an error if a generator expression appears in another location and the path is relative. .. |INTRODUCED_IN_CMAKE_VERSION| replace:: 3.0 .. |WARNS_OR_DOES_NOT_WARN| replace:: warns .. include:: STANDARD_ADVICE.txt .. include:: DEPRECATED.txt
