The cmake_enable_flt.sh script will automatically install the required cross-toolchains required to build FEXLinuxTests, and it will reconfigure the current build folder appropriately. For advanced uses, a shell can be opened by running `nix-shell FEXLinuxTests/shell.nix`, which will make the toolchain available via environment variables.
