CMAKE_TEST_BUILD_DEPENDS
------------------------

.. versionadded:: 4.5

List of directory-scoped build time dependencies for tests.

This property holds a
:ref:`semicolon-separated list <CMake Language Lists>` of targets and/or files
that should be built by ``test_prep/all`` when
:variable:`CMAKE_TEST_BUILD_DEPENDS` is enabled.  A relative file path is
interpreted with respect to the current source directory if the file exists
there, and otherwise with respect to the current binary directory.

Projects may append to this property directly with :command:`set_property` or
:command:`set_directory_properties` to extend ``test_prep/all`` with
directory-scoped build dependencies.
