# Yes, mesa and xorg-libX11 are *build* dependencies.  The library will function correctly
# if they are not present because it loads mesa dynamically only when GLX is used.  When
# OpenGL.framework is used, there is no need to have mesa at runtime.
#
# Clients of this library must link mesa directly and have it listed as their dependency
# in order to use mesa with libepoxy.
