TEST_DEPENDS use scenario is missing
From the documentation it is not quite clear, what is TEST_DEPENDS for, and how it can be used. Probably it is for testing, and follows the same logic as DEPENDS, but I cannot conclude from the docs how to use it.
Yes, these should be documented in the manual. For now, please refer to the API documentation. In this case the basis_project function of which TEST_DEPENDS is an option of.

In case the API documentation is not clear enough, it only says:
List of dependencies, i.e., either names of other BASIS (sub)projects or names of external packages which are only required by the tests.
TEST_DEPENDS and OPTIONAL_TEST_DEPENDS are only looked for when BUILD_TESTING flag is set to ON, i.e., when the source files in the TESTING_DIR (default: test/) are included in the build.
TOOLS_DEPENDS and OPTIONAL_TOOLS_DEPENDS are only looked for when BUILD_APPLICATIONS is set to ON, i.e., when the source files in the TOOLS_DIR (default: tools/) are included in the build.
