[dpdk-dev] Basic question about where to write config for optional feature

[Hideyuki Yamashita <yamashita.hideyuki@ntt-tx.co.jp>]

Hello,

I am planning to propose patch for 
optional feature.

Question:
Where should I write compile switch for 
optional features?

I was planning to add flag to enable 
optional festures into config/common_base
like following:

+#
+# Compile the api statistics library
+#
+CONFIG_RTE_LIBRTE_APISTATS=n

But make build system was gone.
I know that meson system is there instead of make.

But I am not so familiar with meson and 
if someone can teach me where to write flag,
it is highly appreciated.
If you guide documents for "how to write config in meson",
it is also appreciated.

Thanks in advance!
