| INCLUDE_DIRECTORIES |
| ------------------- |
| |
| List of preprocessor include file search directories. |
| |
| This property specifies the list of directories given so far to the |
| :command:`include_directories` command. |
| |
| This property is used to populate the :prop_tgt:`INCLUDE_DIRECTORIES` |
| target property, which is used by the generators to set the include |
| directories for the compiler. |
| |
| In addition to accepting values from that command, values may be set |
| directly on any directory using the :command:`set_property` command. A |
| directory gets its initial value from its parent directory if it has one. |
| The intial value of the :prop_tgt:`INCLUDE_DIRECTORIES` target property |
| comes from the value of this property. Both directory and target property |
| values are adjusted by calls to the :command:`include_directories` command. |
| |
| The target property values are used by the generators to set the |
| include paths for the compiler. |
| |
| Contents of ``INCLUDE_DIRECTORIES`` may use "generator expressions" with |
| the syntax ``$<...>``. See the :manual:`cmake-generator-expressions(7)` |
| manual for available expressions. See the :manual:`cmake-buildsystem(7)` |
| manual for more on defining buildsystem properties. |
