find_library static keyword breaks library detection on Windows with clang #13204

Open kasper93 opened 3 weeks ago

kasper93 commented 3 weeks ago

Looking at the logs, there is nothing even being detected when static is used.

meson.build:

lib = cc.find_library('ws2_32', required: false)

Expected behavior

Library is found with static keyword, at least in one of the value.
