# COMPILE_OPTIONS

List of additional options to pass to the compiler.

This property holds a ;-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.
