# VP Lenneth is a Cocos2d-x 3.x game rendering with the GLES2 programmable
# pipeline (no fixed-function calls), so we link mesa's libGLESv2 -- unlike the
# FF Dimensions wrapper, GLESv1_CM is NOT linked (the game imports zero GLES1
# entry points; its NEEDED libGLESv1_CM is never actually called). SDL2 backs
# the OpenSL ES shim (audio). EGL/glapi/drm_nouveau are the mesa backend. The
# game's C++ runtime and libpng/CRIWARE are bundled inside libMyGame.so /
# libc++_shared.so, so we need no freetype/png/harfbuzz here.
# cjkfont.c needs FreeType to render Chinese/other non-latin LabelTTF text
# (the game's bitmap fonts only carry latin glyphs). Install switch-freetype:
#   sudo dkp-pacman -S switch-freetype
