# HACK: This export of XDG_CACHE_HOME is required to make vcpkg happy.
# This is because vcpkg tries to find a cache directory by:
#   1) checking $XDG_CACHE_HOME
#   2) appending "/.cache" to $HOME
# The problem is, in the Android build environment, neither of those environment variables are set.
# This causes vcpkg to fail; so, we set a dummy $XDG_CACHE_HOME, ensuring that vcpkg is happy.
# (Note that vcpkg appends "/vcpkg" to the cache directory we give it.)
# (And this also works on macOS, despite the fact that $XDG_CACHE_HOME is a Linux-ism.)
