Install packages on cygwin

I use latex for cygwin, installed by the cygwin setup GUI. How can I install other missing package? For example i haven't tikz... I've to manually install it or there is a better solution?

Predrag mentioned TeX Live in his answer. If cygwin is not important for you, then TeX Live has an easy to use installer for Windows that may be found here. On Windows MiKTeX is another popular distribution that is actively maintained. Both include TikZ. If at all possible use one of these two. –  qubyte Feb 14 '12 at 14:24

``````ln -s 'C:\Program Files (x86)\MiKTeX 2.9\miktex\bin\x64\latex.exe'  /usr/local/bin/latex
