mk: add "make examples" target in root makefile
It is now possible to build all projects from the examples/ directory using one command from root directory. Some illustration of what is possible: - build examples in the DPDK tree for one target # install the x86_64-default-linuxapp-gcc in # ${RTE_SDK}/x86_64-default-linuxapp-gcc directory user@droids:~/dpdk.org$ make install T=x86_64-default-linuxapp-gcc # build examples for this new installation in # ${RTE_SDK}/examples directory user@droids:~/dpdk.org$ make examples T=x86_64-default-linuxapp-gcc - build examples outside DPDK tree for several targets # install all targets matching x86_64-*-linuxapp-gcc in # ${RTE_SDK}/x86_64-*-linuxapp-gcc directories user@droids:~/dpdk.org$ make install T=x86_64-*-linuxapp-gcc # build examples for these installations in /tmp/foobar user@droids:~/dpdk.org$ make examples T=x86_64-*-linuxapp-gcc O=/tmp/foobar Signed-off-by: Olivier Matz <olivier.matz@6wind.com> Acked-by: Thomas Monjalon <thomas.monjalon@6wind.com>
