+tests/crosstests.txt: FORCE + echo $(vkd3d_cross_tests) | tr ' ' '\n' > $@
We'll probably want a "$(AM_V_GEN)" in front of that. Note that we could avoid the "tr" dependency with something like "for i in $(vkd3d_cross_tests); do echo $$i; done > $@"
I haven't checked, but I imagine we'll want to add tests/crosstests.txt and tests/shader_tests.txt to .gitignore and CLEANFILES.
