COMPILE_OPTIONS

New in version 3.11.

List of additional options to pass to the compiler.

This property holds a semicolon-separated list of options and will be added to the list of compile flags when this source file builds.

Contents of COMPILE_OPTIONS may use “generator expressions” with the syntax $<...>. See the cmake-generator-expressions(7) manual for available expressions. However, 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:

set_source_files_properties(foo.cpp PROPERTIES COMPILE_OPTIONS "-Wno-unused-parameter;-Wno-missing-field-initializer")

Related properties:

• Prefer this property over COMPILE_FLAGS.

• Use COMPILE_DEFINITIONS to pass additional preprocessor definitions.

• Use INCLUDE_DIRECTORIES to pass additional include directories.

Related commands:

• add_compile_options() for directory-wide settings

• target_compile_options() for target-specific settings
