# wlroots0.19 - the 0.19 series of the wlroots compositor library, slotted
# beside 0.20.
#
# apwc (and dwl-derived compositors generally) track a specific wlroots
# series and do not build against the next one - the API changes between
# minor releases. 0.19 and 0.20 install versioned names
# (libwlroots-0.19.so, include/wlroots-0.19, wlroots-0.19.pc), so both can
# be installed at once without owning any of the same files.
#
# Configured to match what apwc is actually developed against: XWayland on,
# DRM and libinput backends, GLES2 renderer, libseat sessions, GBM
# allocator. No Vulkan renderer - that is what the reference build uses too.

# Every one of these is an actual DT_NEEDED of libwlroots-0.19.so, not a
# guess: libEGL/libGLESv2 come from libglvnd (mesa only ships the _mesa
# vendor libraries), libgbm from mesa, libudev from eudev, libseat from
# seatd, libxcb-ewmh/icccm from xcb-util-wm, the other xcb extensions from
# libxcb itself. hwdata is read at runtime for monitor names, and Xwayland
# is exec'd by the xwayland backend.
