I am using the ArrayFire binaries provided by my Linux distro (Artix Linux, i.e. Arch Linux without Systemd). I want to build the examples, and I get linker errors.
The library is installed here:
> ls /usr/lib/libaf*
/usr/lib/libaf.debug /usr/lib/libaf.so.3.9.0 /usr/lib/libafcpu.so.3 /usr/lib/libafcuda.so /usr/lib/libafopencl.debug /usr/lib/libafopencl.so.3.9.0
/usr/lib/libaf.so /usr/lib/libafcpu.debug /usr/lib/libafcpu.so.3.9.0 /usr/lib/libafcuda.so.3 /usr/lib/libafopencl.so
/usr/lib/libaf.so.3 /usr/lib/libafcpu.so /usr/lib/libafcuda.debug /usr/lib/libafcuda.so.3.9.0 /usr/lib/libafopencl.so.3
I copy the examples directory in my home, and setup an out-of-source build:
~/examples
~/examples_build
I run cmake specifying the library path:
examples_build> cmake -DArrayFire_DIR=/usr/lib/ ../examples/

When I run make I have linker errors:

Is it possible that these errors are due to missing features in my distro build of ArrayFire?
What else could be the problem?
