如何通过CMake强制c ++编译器使用不同已安装软件包的版本之一? [英] How to force c++ compiler use one of different installed package's versions, using CMake?

问题描述

我在计算机上安装的ROS Fuerte使用opencv 2.2.我想使用刚安装的2.4.9版本.它的位置是/home/polar/soft/lib/opencv/opencv-2.4.9/build/lib.

ROS Fuerte I installed on my machine uses opencv 2.2. I would like to use 2.4.9 version just installed. Its location is /home/polar/soft/lib/opencv/opencv-2.4.9/build/lib.

请问如何使用CMake做到这一点? 通过我的搜索，看来find_library可以解决问题，但无法使其正常工作.

How to do that with CMake, please? From my search, it seems that find_library would solve the issue, but was not able to make it work.

=====我在这样的cpp代码中包含opencv

===== I include opencv in my cpp codes like this

  #include <opencv2/core/core.hpp>
    #include <opencv2/highgui/highgui.hpp>
    #include <opencv2/opencv.hpp>
    #include "opencv2/imgproc/imgproc.hpp"

endforeach(file2link)

ADD_SUBDIRECTORY(src)

推荐答案

所以，我怀疑target_link_libraries(${file2link} .... ${OpenCV_LIB}) 是问题所在:OpenCV_LIB似乎已分配.

So, as I suspected, target_link_libraries(${file2link} .... ${OpenCV_LIB}) was the problem: OpenCV_LIB seems like allocated.

现在，我正在以这种方式链接opencv，并且可以正常工作:

Now, am linking opencv in this way and it works:

find_package(OpenCVV 2.4.9 PATHS /home/polar/soft/lib/opencv/opencv-2.4.9/cmake)
...
target_link_libraries(${file2link}  .... ${OpenCVV_LIB})

实际上我只是用了另一个名字，但OpenCV.

In fact I just used another name but OpenCV.
