Subject: examples: use pkg-config in makefiles
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=22119c4591a0;p=dpdk.git

examples: use pkg-config in makefiles

Change the example app Makefiles to query if DPDK is installed and
registered using pkg-config. If so, build directly using pkg-config info,
otherwise fall back to using the original build system with RTE_SDK and
RTE_TARGET

This commit changes the makefiles for the basic examples, i.e. those which
do not have multiple subdirectories underneath the main examples dir.
Examples not covered are:

* ethtool
* multi_process
* performance-thread
* quota_watermark
* netmap_compat
* server_node_efd
* vm_power_manager
