OpenCV imwrite 函数导致'undefined symbol'

我正在开发一个软件，它由一些带有python绑定的核心C++代码组成。C++代码已经使用了很多OpenCV，但现在我正在尝试将图像保存在两者之间的某个地方，并且我似乎无法使用imwrite功能。将其添加到main中.cpp并使用"默认"构建在eclipse中进行编译是有效的，但是为了将其与现有的Python代码一起使用，我需要使用CMake进行构建。这再次编译正常，但是当我从 Python 类调用代码时，出现此错误：

ImportError: /.../pythonCPP.so: undefined symbol: _ZN2cv7imwriteERKNS_6StringERKNS_11_InputArrayERKSt6vectorIiSaIiEE

我搜索了这个，从我能收集到的信息来看，这似乎通常源于某种链接问题。我不知道从哪里开始在 CMake 文件中查找或添加任何标志。我在 Ubuntu 16.04 64 位上使用 OpenCV 3.2.0。

这是相应的CMakeLists.txt：
