Static build fails on linux

[bog-dan-ro]

I tried to build epoxy as a static library (-Ddefault_library=static) but it fails to link:

$ ninja

I sometimes have this problem specifically with meson/ninja. Not sure if this is related to the issue here
but I remember having had projects with GNU configure that could be built static, but the meson/ninja
way failed.

add "static: true" to the dependency lines eg.
gl_dep = dependency('gl', required: false, static: true)
