CMP0076 — CMake 3.31.1 Documentation

# CMP0076

Added in version 3.13.

The `target_sources()` command converts relative paths to absolute.

In CMake 3.13 and above, the `target_sources()` command now converts relative source file paths to absolute paths in the following cases:

- Source files are added to the target's `INTERFACE_SOURCES` property.

- The target's `SOURCE_DIR` property differs from `CMAKE_CURRENT_SOURCE_DIR`.

A path that begins with a generator expression is always left unmodified.

This policy provides compatibility with projects that have not been updated to expect this behavior. The `OLD` behavior for this policy is to leave all relative source file paths unmodified. The `NEW` behavior of this policy is to convert relative paths to absolute according to above rules.

This policy was introduced in CMake version 3.13. It may be set by `cmake_policy()` or `cmake_minimum_required()`. If it is not set, CMake warns, and uses `OLD` behavior.

Note

The `OLD` behavior of a policy is `deprecated by definition` and may be removed in a future version of CMake.
