SOURCES — CMake 4.4.3 Documentation

# SOURCES

Added in version 4.4.

This specifies the list of paths to sources for the file set. The `target_sources()` command sets or adds to the `SOURCES` file set property for the file sets defined with the `PRIVATE` or `PUBLIC` keyword and is the usual way to manipulate it.

Contents of `SOURCES` may use `generator expressions`.

Each file must be in one of the base directories, or a subdirectory of one of the base directories. If relative paths are specified, they are considered relative to the target's source directory.

The following behavior applies for the `SOURCES` and `INTERFACE_SOURCES` file set properties, dependent on the value of the `SCOPE` file set property:

`PRIVATE`

  Only the `SOURCES` property can be set. Any change to the `INTERFACE_SOURCES` property will be ignored.

`PUBLIC`

  `SOURCES` and `INTERFACE_SOURCES` properties will always have the same content.

`INTERFACE`

  Only the `INTERFACE_SOURCES` property can be set. Any change to `SOURCES` property will be ignored.
