Simple WasmBoxC Library Example

This shows how to easily sandbox a real-world library using WasmBoxC. Specifically we sandbox the zlib compression library.

To follow along with this, you can clone this gist and then do the following commands.

	# This isn't meant to be a fully featured implementation. It's just a small playground project.
	# Use `cmake -Bbuild -S. -GNinja` to generate the project
	# Then use `cmake --build build --target package` to generate a .appimage file ready to go
	# This project DOES do dangerous things and tries to download the linuxdeploy tool directly.
	# When this makes it into IXM, it will be expected that users have the linuxdeploy tool installed to some location.
	# It will NOT download and execute something from the internet.
	cmake_minimum_required(VERSION 3.16)
	project(summon-test LANGUAGES CXX VERSION 0.1.0)

	add_executable(app)

	all: hello hello.fatbin hello.ptx dyload
	hello: kernel.cu
	nvcc -std=c++11 -arch sm_60 kernel.cu -o hello -lcuda
	hello.fatbin: kernel.cu
	nvcc -std=c++11 -arch sm_60 kernel.cu -o hello.fatbin --fatbin -lcuda
	hello.ptx: kernel.cu
	nvcc -std=c++11 -arch sm_60 kernel.cu -o hello.ptx -ptx
	dyload: hello.fatbin load.cu
	nvcc -std=c++11 -arch sm_60 load.cu -o dyload -lcuda
	clean:

	#include <stdio.h>
	#include <stdlib.h>
	#include <string.h>
	#include <dlfcn.h>

	int main(int argc, char** argv)
	{
	void *handle;
	void (func_print_name)(const char);
