Here is a dependency list taken from a gentoo ebuild (I don't use ubuntu, sorry):
CDEPEND="x11-libs/wxGTK:2.8[X,opengl]"
DEPEND="${CDEPEND}
>=dev-util/cmake-2.6.0
>=dev-libs/boost-1.40[python?]
app-arch/xz-utils
dev-doc? ( app-doc/doxygen )"
so, wxGTK, cmake, boost, xz-utils (for LZMA), and if you want documentation, doxygen. Not sure if that helps or not.
