Compiling litecoind on Ubuntu 15.04 I am trying to compile litecoind on Ubuntu 15.04 and I stuck here:

/litecoin/src$ make -f makefile.unix USE_UPNP=-
make: makefile.unix: No such file or directory 
make: *** No rule to make target 'makefile.unix'.  Stop.


I found some a little bit different ways to compile litecoind, but every time I have problems with "makefile.unix". Can someone help me?
The build system has changed to autotools in later versions of Litecoin. 

The process now looks like this: 

./autogen.sh 
./configure
make -j4 
make install # optional


There's up to date instructions in detail in build-unix.md.
