| COMPILE_DEFINITIONS |
| ------------------- |
| |
| Preprocessor definitions for compiling a directory's sources. |
| |
| This property specifies the list of options given so far to the |
| :command:`add_compile_definitions` (or :command:`add_definitions`) command. |
| |
| The ``COMPILE_DEFINITIONS`` property may be set to a semicolon-separated |
| list of preprocessor definitions 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). |
| |
| This property will be initialized in each directory by its value in the |
| directory's parent. |
| |
| CMake will automatically drop some definitions that are not supported |
| by the native build tool. |

| |
| Contents of ``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. |
| |
| The corresponding :prop_dir:`COMPILE_DEFINITIONS_<CONFIG>` property may |
| be set to specify per-configuration definitions. Generator expressions |
| should be preferred instead of setting the alternative property. |
