| 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 and below (whether added before or after this command is invoked). |
| 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| This command has been superseded by alternatives: |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. |
| |
| See the :manual:`cmake-buildsystem(7)` manual for more on defining |
| buildsystem properties. |
