RIME(中州韻輸入法引擎) is mainly a Traditional Chinese input method engine.
project: http://rime.im/
RIME split its devlopment source into a few sections, here we need librime.
In librime source, there are two directory, brise and librime.
According to your distribution, you might need brise+librime package(openSUSE) or only librime which includes brise at /usr/share/brise.
If your distribution doesn't have one you need to download librime and put brise directory into /usr/share/brise.
If you're a distribution packager, ask maintainer of librime to add brise sub-package.
Boost is a RIME dependency, so without boost >= 1.46.1, you will not ble to install librime-devel.
Generally it means, distros that are a little old like openSUSE 11.4 or Ubuntu 10.10 might not be possible to build or install.
*cmake
*gcc-c++
*fcitx-devel with all three skins
some distro like openSUSE split a fcitx-skin-classic and a fcitx-skin-dark, so you need them.
*librime-devel
*brise
*hicolor-icon-theme
optional, for directory ownership.
