Make python modules dependency detection explicit
sdbusplus requires python modules like infection, mako & pyyaml
and in the current state, it checks for those dependency while it
tries to compile the example and fails at the following step.
example/meson.build:48:0: ERROR: Command "sdbus++-gendir --tool
sdbus++ --output /sdbusplus/build/example net" failed with status 1.
And we need to check the meson logs to figure out that a python
module is missing.
The intent behind this commit is to leverage the python module
support in meson to make the dependency check explicit and clear.
Tested :
Tested this both on ubuntu & fedora
1. Without required packages
Program python3 (inflection, yaml, mako) found: NO
meson.build:17:0: ERROR: python3 is missing modules: inflection, yaml, mako
2. With required packages
Program python3 (inflection, yaml, mako) found: YES (/usr/bin/python3) modules: inflection, yaml, mako
