| add_compile_definitions | |
| ----------------------- | |
| .. versionadded:: 3.12 | |
| Add preprocessor definitions to the compilation of source files. | |
| .. code-block:: cmake | |
| add_compile_definitions(<definition> ...) | |
| Adds preprocessor definitions to the compiler command line. | |
| The preprocessor definitions are added to the :prop_dir:`COMPILE_DEFINITIONS` | |
| directory property for the current ``CMakeLists`` file. They are also added to | |
| the :prop_tgt:`COMPILE_DEFINITIONS` target property for each target in the | |
| current ``CMakeLists`` file. | |
| 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). | |
| .. versionadded:: 3.26 | |
| Any leading ``-D`` on an item will be removed. | |
| .. |command_name| replace:: ``add_compile_definitions`` | |
