Output directory in which to build |XXX| target files.

This property specifies the directory into which |xxx| target files should be built. The property value may use generator expressions. Multi-configuration generators (Visual Studio, Xcode, Ninja Multi-Config) append a per-configuration subdirectory to the specified directory unless a generator expression is used.

This property is initialized by the value of the |CMAKE_XXX_OUTPUT_DIRECTORY| variable if it is set when a target is created.
