Description

iwyu-target-cmake can be used to scan individual source files for include-what-you-use violations. The check is added to target and automatically run over all of it its source files.

Usage

include-what-you-use-target-cmake works by scanning source files for #include statements and then checks the passed include directories for files matching the name of files specified in the #include statements.

Checking a target

`iwyu_target_sources`

Examine the sources attached to TARGET for include-what-you-use violations. The compiler flags as indicated in the arguments are passed to include-what-you-use to determine whether or not included files are not necessary.

TARGET: Target to check
[Optional] CHECK_GENERATED: Also check generated files, off by default.
[Optional] WARN_ONLY: Don't abort the build on violations, just warn.
[Optional] FORCE_LANGUAGE: Treat source files for this target as either C or CXX.
[Optional] EXTERNAL_INCLUDE_DIRS: System-level include directories (will not be transitively examined).
[Optional] INTERNAL_INCLUDE_DIRS: Include directories in this project (will be transitively examined).
[Optional] DEFINES: Definitions to set when preprocessing.
[Optional] CPP_IDENTIFIERS: Identifiers which indicate that a header file scanned is always C++.
[Optional] DEPENDS: Targets to run or source files to generate before checking the sources for violations.
