== Compilation for Android ==
ndk-build BUILD_GPLV3_ZRTP=1  -j5


== Compilation for Desktop version ==
First ortp: ./autogen.sh && ./configure --enable-zrtp && make -j5 && sudo make install
Then mediastreamer2: ./autogen.sh && ./configure && make -j5 && sudo make install
Finally linphone: ./autogen.sh && ./configure --enable-external-ortp && make -j5 && sudo make install
