OpenCPN on Raspberry Pi2

[yaphone]

I use the Debian system and I follow this website (Compiling - Linux | Official OpenCPN Homepage) to compile OpenCPN .
I have some problems :
1.
pi@raspberrypi ~ $ sudo apt-get install build-essential cmake gettext git-core gpsd gpsd-clients libgps-dev wx-common libwxgtk3.0-dev libglu1-mesa-dev libgtk2.0-dev wx3.0-headers libbz2-dev libtinyxml-dev libportaudio2 portaudio19-dev
正在讀取套件清單... 完成
正在重建相依關係
正在讀取狀態資料... 完成
E: 找不到套件 libwxgtk3.0-dev
E: Couldn't find any package by regex 'libwxgtk3.0-dev'
E: 找不到套件 wx3.0-headers
E: Couldn't find any package by regex 'wx3.0-headers'

I try to do download these two packages in debian web but are the same problems, how can I solve the problem?

2.
pi@raspberrypi ~ $ cd OpenCPN
pi@raspberrypi ~/OpenCPN $ cd build
pi@raspberrypi ~/OpenCPN/build $ cmake ..
