# The Emscripten SDK at https://github.com/emscripten-core/emsdk/
# contains a Makefile in the docker/ subdirectory that can be used to create the
# required base image using:
#
#   make version=2.0.33 build
#
# Note that emscripten is supposed to automatically install to $(em-config CACHE)/sysroot, but
# apparently this currently breaks due to conflicting compatibility headers.
# Using $(em-config CACHE)/sysroot/usr seems to work, though, and still has cmake find the
# dependencies automatically.
