| add_definitions | |
| --------------- | |
| Add ``-D`` define flags to the compilation of source files. | |
| .. code-block:: cmake | |
| add_definitions(-DFOO -DBAR ...) | |
| Adds definitions to the compiler command line for targets in the current | |
| directory, whether added before or after this command is invoked, and for | |
| the ones in sub-directories added after. This command can be used to add any | |
| flags, but it is intended to add preprocessor definitions. | |
| .. note:: | |
| This command has been superseded by alternatives: | |
| * Use :command:`add_compile_definitions` to add preprocessor definitions. | |
| * Use :command:`include_directories` to add include directories. | |
| * Use :command:`add_compile_options` to add other options. | |
| Flags beginning in ``-D`` or ``/D`` that look like preprocessor definitions are | |
| automatically added to the :prop_dir:`COMPILE_DEFINITIONS` directory | |
| property for the current directory. Definitions with non-trivial values | |
| may be left in the set of flags instead of being converted for reasons of | |
| backwards compatibility. See documentation of the | |
| :prop_dir:`directory <COMPILE_DEFINITIONS>`, | |
| :prop_tgt:`target <COMPILE_DEFINITIONS>`, | |
| :prop_sf:`source file <COMPILE_DEFINITIONS>` ``COMPILE_DEFINITIONS`` | |
| properties for details on adding preprocessor definitions to specific | |
| scopes and configurations. | |
