-# Cross Compiling for AArch64
-
-- To cross compile for AArch64, first adjust the variables set in cmake/setenv-arm64-cross.sh.
-  - `export CROSS=<arm-cross-compiler-dir>/bin/aarch64-linux-gnu-`
-  - `export CROSS_SYS=<arm-cross-compiler-system-dir>`
-  - `export BOOST_PATH=<boost-source-dir>`
-- Set the environment variables:
-  - `source cmake/setenv-arm64-cross.sh`
-- Configure Vectorscan:
-  - `mkdir <build-dir-name>`
-  - `cd <build-dir>`
-  - `cmake -DCROSS_COMPILE_AARCH64=1 <hyperscan-source-dir> -DCMAKE_TOOLCHAIN_FILE=<hyperscan-source-dir>/cmake/arm64-cross.cmake`
-- Build Vectorscan:
-  - `make -jT` where T is the number of threads used to compile.
-  - `cmake --build . -- -j T` can also be used instead of make.
