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. Use COMPILE_DEFINITIONS to pass additional preprocessor definitions and INCLUDE_DIRECTORIES to pass additional include directories.

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.


This property should be preferred over the COMPILE_FLAGS property.
