make: *** [Makefile:101: install] Error 2

Start by reading pre_tasks.yml around line 36 and roles/davinci_resolve/tasks/main.yml around lines 25 and 32, then review the Makefile install target. Reproduce with make install TAGS=davinci_resolve on the davinci branch and verify that the installation completes without the conditional error.
