SYNOPSIS
\t$NAME [-h|--help] [toolchain|build|qemu|test|all]
DESCRIPTION
\tCross compile using a cross toolchain.
\tYou MUST define the following variables before running this script:
\t* TARGET:
\t\tx86_64
\t\taarch64-linux-gnu aarch64_be-linux-gnu
\t\tarm-linux-gnueabihf armv8l-linux-gnueabihf arm-linux-gnueabi
\t\tarmeb-linux-gnueabihf armeb-linux-gnueabi
\t\tmips32 mips32el
\t\tmips64 mips64el
OPTIONS
\t-h --help: show this help text
\ttoolchain: download, unpack toolchain and generate CMake toolchain file
\tbuild: toolchain + build the project using the toolchain file (note: remove previous build dir)
\tqemu: download, unpack and build qemu
\ttest: qemu + run all executable using qemu (note: don't build !)
\tall: build + test (default)
EXAMPLES
* Using export:
export TARGET=aarch64-linux-gnu
$0
* One-liner:
TARGET=aarch64-linux-gnu $0"
