I'm trying to compile skia to compile aseprite on Ubuntu 19.10, I keep getting the error

all the posts I've found have said to install libgl1-mesa-dev using apt-get, but I've already done that and I'm still getting the error. I've also tried running install_dependencies.sh in the tools folder, which installed a bunch of other stuff.
