COMPILE_OPTIONS

.. versionadded:: 4.4

List of additional options to pass to the compiler.

This property holds a :ref:semicolon-separated list <CMake Language Lists> of options and will be added to the list of compile flags when the sources of this file set are built. The options will be added after target-wide options and source level ones.

Contents of COMPILE_OPTIONS may use "generator expressions" with the syntax $<...>. See the :manual:cmake-generator-expressions(7) manual for available expressions. However, :generator:Xcode does not support per-config per-source settings, so expressions that depend on the build configuration are not allowed with that generator.

Usage example:

.. code-block:: cmake

set_property(FILE_SET SOURCES TARGET foo PROPERTY COMPILE_OPTIONS "-Wno-unused-parameter;-Wno-missing-field-initializer")
