[dpdk-dev] JSON compilation in examples/vm_power_manager

[Thomas Monjalon]

Hi Dave,

In examples/vm_power_manager/Makefile, jansson lib availability
is detected with pkg-config --exists.
As we have seen for telemetry lib, we can detect jansson
for the wrong arch and enable it no matter the arch being compiled.

The solution was to disable it in Makefile and use meson for
reliable dependency detection.

Would you like to do the same for this app?
