Hi Chris,
You also need to add your library as a dependency on the
sel4test-driver executable:
target_link_libraries(
sel4test-driver
PUBLIC
sel4_autoconf
muslc
sel4
sel4runtime
sel4allocman
sel4vka
sel4utils
sel4rpc
sel4test
sel4platsupport
sel4muslcsys
sel4testsupport
chrises_lib
PRIVATE sel4test-driver_Config
)
Alternatively adding it as a dependency for any of the libraries that
sel4test-driver already depends on should also cause it to link.
