Trying to compile 0.21.1 on Apple M1 architecture (Mac Mini M1 2020, Big Sur 11.3.1), I get the following error when running make in the depends directory:
ERROR: Feature 'system-zlib' was enabled, but the pre-condition 'libs.zlib' failed.
The error also happens when I check out the head of master, instead of the v0.21.1 tag.
It seems QT-related, since running make NO_QT=1 in the depends succeeds.
Any advice?
