Where to set board library dependency on linux?

It's killing me to try to run this on Ubuntu...

With Ubuntu 16.04.03 kernel 4.7, I finally got the board to install, aocl diagnose all good, jtagconfig have some trouble but resolved, compile example code .aocx file no problem,

and now, it's loading the wrong board mmd.....

Initializing OpenCL
Error: Could not load board library /home/matthew/intelFPGA/17.0/hld/board/c5gt/linux64/lib/libaltera_c5gt_mmd.so 

Not sure why it's loading from 17.0 which I removed and replaced with 17.1 pro.

PATH: /home/matthew/intelFPGA_pro/17.1/quartus/bin:/home/matthew/intelFPGA_pro/17.1/hld/linux64/bin:/home/matthew/intelFPGA_pro/17.1/hld/bin:/home/matthew/intelFPGA_pro/17.1/qsys/bin:...

LD_LIBRARY_PATH: /home/matthew/intelFPGA_pro/17.1/hld/host/linux64/lib:/home/matthew/intelFPGA_pro/17.1/hld/board/a10_ref/linux64/lib

The section "Linking to the ICD Loader Library on Linux" in the programming guide said: modify theMakefile,

but it's not clear what to modify and I don't have a clue. On windows10 I just set the registry key and it work right away...

Probably a simple path setting can fix this but I just can't find it:evil:

Any help is appreciated!

----------------------------------------

Might as well talk about how to get this thing working on Ubuntu 16.04:

Kernel 4.13 won't work so I install 4.4, it can install board driver but there's other issue(internet) so I switch to 4.7.

Jtag usb device can't be detected (shows up in lsusb but can't find device with jtagconfig)

Use the following command to correct it:

$ sudo killall -9 jtagd
$ sudo mount --bind /dev/bus /proc/bus
$ sudo ln -s /sys/kernel/debug/usb/devices /proc/bus/usb/devices
$ sudo <quartus_directory>/bin/jtagd
$ sudo <quartus_directory>/bin/jtagconfig
