| add_compile_definitions |
| ----------------------- |
| |
| Add preprocessor definitions to the compilation of source files. |
| |
| .. code-block:: cmake |
| |
| add_compile_definitions(<definition> ...) |
| |
| Adds preprocessor definitions to the compiler command line for targets in the |
| current directory and below (whether added before or after this command is |
| invoked). See documentation of the :prop_dir:`directory <COMPILE_DEFINITIONS>` |
| and :prop_tgt:`target <COMPILE_DEFINITIONS>` ``COMPILE_DEFINITIONS`` properties. |
| |
| Definitions are specified using the syntax ``VAR`` or ``VAR=value``. |
| Function-style definitions are not supported. CMake will automatically |
| escape the value correctly for the native build system (note that CMake |
| language syntax may require escapes to specify some values). |
| |
| Arguments to ``add_compile_definitions`` 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. |
