我只想从系统中删除所有的OpenCV痕迹，所以我可以重新开始..

整个故事

很久以前，我首先从https://launchpad.net/~gijzelaar/+archive/opencv2安装了python-opencv和libopencv(2.1我认为)。那时候我只尝试过python-opencv，它工作得很好(我没有尝试使用OpenCV使用C代码)

然后我最近试图从源代码安装OpenCV 2.3.1，但是在编译我自己的C代码(使用OpenCV)的时候，它给了我关于libgtk没有安装的错误，也破坏了我早期运行的python opencv代码

所以我安装了libgtk2-dev库并再次编译并安装了OpenCV 2.3.1。

错误仍然发生，所以我删除了我正在运行cmake，make等的untarred OpenCV目录。我没有卸载(我现在意识到是我的错误)

而是从这里安装ubuntu opencv 2.3软件包(包括所有依赖项)：https://launchpad.net/~gijzelaar/+archive/opencv2.3

现在问题是我仍然得到相同的错误，当我编译我的C代码，其中包括OpenCV，并且错误仍指向我的(删除)OpenCV源文件夹：

OpenCV Error: Unspecified error (The function is not implemented. Rebuild the library with Windows,GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian,install libgtk2.0-dev and pkg-config,then re-run cmake or configure script) in cvNamedWindow,file /home/anant/opencv/OpenCV-2.3.1/modules/highgui/src/window.cpp,line 275
terminate called after throwing an instance of 'cv::Exception'
  what():  /home/anant/opencv/OpenCV-2.3.1/modules/highgui/src/window.cpp:275: error: (-2) The function is not implemented. Rebuild the library with Windows,then re-run cmake or configure script in function cvNamedWindow

可以看到错误仍然指向从我编译和安装OpenCV的目录

有没有办法完全删除OpenCV编译版本的所有痕迹，只需保留ubuntu软件包中的文件？如前所述，我没有“卸载”，并且(愚蠢地)删除了install-manifest

编辑：
我再次运行包管理器，发现并不是所有的ppa的opencv包都已经正确安装了。所以我做了一个sudo apt-get再次安装opencv，现在我得到这个错误：
