Not sure about this, but it looks you’ve installed a 32 bits armhf library while you are on a TX1. This is more targeted to TK1. Older versions of L4T for TX1 have been using 32 bits userland, but the linker message makes me thinking to 32bits library not suitable for 64bits system.
If you can find a package pylon-5.x.x.x-aarch64 and install it it would probably be the easiest way.
I cannot tell how to run 32bits libraries on a 64bits system, albeit this might not be impossible.
If you cannot get the binary aarch64 version, you can try to get the sources of pylon and compile by yourself on TX1, this would produce 64bits libraries and you would be able to link your samples against these 64bits libraries.
It works fine at my side with the following up2date versions:
