INCLUDE_DIRECTORIES — CMake 4.4.3 Documentation

# INCLUDE_DIRECTORIES

Added in version 3.11.

List of preprocessor include file search directories.

This property holds a semicolon-separated list of paths and will be added to the list of include directories when this source file builds. These directories will take precedence over directories defined at target level except for `Xcode` generator due to technical limitations.

Relative paths should not be added to this property directly.

Contents of `INCLUDE_DIRECTORIES` 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.
