-The :command:`target_include_directories`, :command:`target_compile_definitions`
-and :command:`target_compile_options` commands specify the build specifications
-and the usage requirements of binary targets.  The commands populate the

-:prop_tgt:`INTERFACE_INCLUDE_DIRECTORIES`, :prop_tgt:`INTERFACE_COMPILE_DEFINITIONS`
-and :prop_tgt:`INTERFACE_COMPILE_OPTIONS` target properties.

-Each of the commands has a ``PRIVATE``, ``PUBLIC`` and ``INTERFACE`` mode.  The

-property value.

-Entries in the :prop_tgt:`COMPILE_DEFINITIONS` are prefixed with ``-D`` or
-``/D`` and added to the compile line in an unspecified order.  The
-:prop_tgt:`DEFINE_SYMBOL` target property is also added as a compile
-definition as a special convenience case for ``SHARED`` and ``MODULE``
-library targets.
-
-Entries in the :prop_tgt:`COMPILE_OPTIONS` are escaped for the shell and added
-in the order of appearance in the property value.  Several compile options have
-special separate handling, such as :prop_tgt:`POSITION_INDEPENDENT_CODE`.
