- COMPILE_DEFINITIONS
- -------------------
- Preprocessor definitions for compiling a directory's sources.
- This property specifies the list of options given so far to the
- :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.
- .. include:: /include/COMPILE_DEFINITIONS_DISCLAIMER.txt
- 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.
