Using eval like this can sometimes have weird consequences. I would recommend
rewriting this without eval. I think something like this should work. It may
change the order of elements, but that shouldn't matter here.
$1_SRCS_WITHOUT_ROOTS := $$(foreach i, $$($1_SRC), \
$$(patsubst $$i/%,%, $$(filter $$i/%, $$($1_SRCS))))
