Make error on aarch64

[FSet89]

I am trying to build on a Aarch64 architecture:

git clone https://github.com/uzh-rpg/fast.git
cd fast
mkdir build
cd build
cmake ..
make

I get the following error on make:

c++: error: unrecognized command line option ‘-mmmx’ c++: error: unrecognized command line option ‘-msse’; did you mean ‘-fdse’? c++: error: unrecognized command line option ‘-msse’; did you mean ‘-fdse’? c++: error: unrecognized command line option ‘-msse2’ c++: error: unrecognized command line option ‘-msse3’ c++: error: unrecognized command line option ‘-mssse3’

Could you please give -fsee a try? I am not sure if that will solve it

I was able to build on an arm64 architecture (jetson nano with Ubuntu 18.04) using catkin build. Two things:

1. In CMakeLists.txt, note at the top it only does the arm build if the environment variable ARM_ARCHITECTURE is defined. So the first step is do export ARM_ARCHITECTURE=true in the terminal you will catkin build in.
2. The CMakeList.txt is set up for an old version of the odroid I guess, so replace SET(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS} -O3 -mfpu=neon -march=armv7-a") with SET(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS} -O3 -march=armv8-a")

This worked for me, hope it helps!
