我认为here发生的问题几乎相同。
我做了这个problem的评论和答复，在CMakeLists.txt中添加了set（OpenCV_DIR xxxxx / opencv-3.4.5 / build）……但仍然是与下面相同的错误。
有人可以帮助我吗？首先谢谢你！
这是我的CMakeLists.txt：
let number = (Number(n) === n && n % 1 !== 0) ? eval(parseFloat(n).toFixed(3)) : n;
这是CMake的日志。似乎成功了。
cmake_minimum_required(VERSION 3.1)
# Enable C++11
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED TRUE)
# Define project name
project(xxxx)
set(OpenCV_DIR xxxxx/opencv-3.4.5/build)
find_package(OpenCV REQUIRED)

message(STATUS " include path: ${OpenCV_INCLUDE_DIRS}")

但是使失败。日志如下：

答案 0 :(得分：0)
不太确定，但是您是否尝试更改
$this->container->view->getEnvironment()->addGlobal('old', $_SESSION['old']);
$_SESSION['old'] = $request->getParams();
应该不是
set(OpenCV_DIR xxxxx/opencv-3.4.5/build)
或者只是尝试预先构建opencv，然后将其链接到您的可执行文件。
EDIT1：
来自opencv_root_dir / build
set(OpenCV_DIR xxxxx/opencv-3.4.5/)
然后
cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..
# use 3 cores to compile
make -j3
添加到您的cmake文件中：
# will install it to /usr/local )
sudo make install
还没有测试它，但是它对我的项目很有帮助。 好处是您不必每次都重建所有的opencv文件。 我也使用* .so文件进行链接。 * .a不适用于我，但您可以自己尝试。
