我打算用cmake安装opencv,当我用cmd在debug文件夹中输入mingw32-make时,出现这个错误,有人能帮我吗?

当我试图运行一个使用opencv库的Java项目时,我正在使用Windows 7并获得此异常:

我尝试在我的Windows10 PC上构建opencv库。我设法使用cmake从源代码生成所有内容。(没有红色,没有错误)。当我尝试使用mingw (mingw32-make install)构建所有内容时,它开始构建,一段时间后,我得到以下错误。

我已经成功地使用MSYS2 / MinGW64 / CMake工具构建了一个MSYS2项目。现在我想在Visual中编辑和调试它,因为它是一个很好的IDE和Windows中的默认开发工具。遗憾的是,我无法在Visual中构建该项目,因为它找不到库。
这里是我使用的CMakeLists.txt文件,除其他外,我指定了包含文件夹、链接文件和链接目录的位置:
# src/CMakeLists.txt
cmake_minimum_required(VERSION 3.3 FATAL_ERROR)
# Project name and current version

我构建了一个基于的静态opencv库,之后我想为我的应用程序调用静态opencv库。但是,应用程序似乎无法链接静态opencv库,并给出以下警告:
