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.
