# PlatformTools enables to deal with tools that perform functionality cross-platform
# For example, the AssetProcessor can generate assets for other platforms. For the
# asset processor to be able to provide that, it requires to have the funcionality enabled.
# This cmake file provides an entry point to discover variables that will allow to enable
# the different platforms and variables that can be passed to enable those platforms to the
# code.

# Discover all the platforms that are available
