[Solved] Can't run sikuli IDE

我的系統環境是 ubuntu 16.10 64bit，這兩天裝 sikuli 時出現以往沒遇過的問題，記錄下來以免下次又遇到。
安裝方式大致說一下

1. 安裝 jdk
2. 安裝 sikuli: java -jar sikulixsetup-1.1.0.jar
3. 執行 runsikulix 時出現下列錯誤 (libopencv_core.so not found 或是 libtesseract.so not found)

[info] runcmd: lsb_release -i -r -s

4. 安裝 opencv, tesseract （圖形處理函式庫跟OCR圖形文字辨識函式庫)

sudo apt-get install libopencv-dev
sudo apt-get install tesseract-ocr

5. 執行 runsikulix 時出現下列錯誤 (錯誤像擠牙膏一樣，擠了才出來）

running SikuliX: -Xmx512M -Dfile.encoding=UTF-8 -Dsikuli.FromCommandLine
-jar ./sikulix.jar
[info] runcmd: lsb_release -i -r -s
[info] HotkeyManager: add Capture Hotkey: CTRL+SHIFT 2 (50, 3)
[info] HotkeyManager: add Abort Hotkey: ALT+SHIFT C (67, 9)
[error] RunTimeIDE:  *** terminating: command 'wmctrl' is not executable
command 'xdotool' is not executable
please check the Availability!

6. 安裝 wmctrl, xdotool

sudo apt-get install wmctrl
sudo apt-get install xdotool

7. done
