INTERFACE_SOURCES

.. versionadded:: 4.4

List of interface sources to compile into consuming targets. The :command:target_sources command sets or adds to the INTERFACE_SOURCES file set property for the file sets defined with the PUBLIC or INTERFACE keyword and is the usual way to manipulate it.

Contents of INTERFACE_SOURCES may use :manual:generator expressions <cmake-generator-expressions(7)>.

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 :prop_fs:SOURCES and INTERFACE_SOURCES file set properties, dependent on the value of the :prop_fs:SCOPE file set property:

PRIVATE Only the :prop_fs:SOURCES property can be set. Any change to the INTERFACE_SOURCES property will be ignored.

PUBLIC :prop_fs:SOURCES and INTERFACE_SOURCES properties will always have the same content.

INTERFACE Only the INTERFACE_SOURCES property can be set. Any change to the :prop_fs:SOURCES property will be ignored.
