cmake has errors:

[RyanCV]

I set the path of opencv in CMakeList.txt as following:

#find_package( OpenCV REQUIRED )
set(OpenCV_LIBS "/cluster/6.2/opencv/2.4.10/lib/")
set(OpenCV_INCLUDE_DIRS "/cluster/6.2/opencv/2.4.10/include")
set(OpenCV_VERSION "2.4.10")
message("Open CV version is ${OpenCV_VERSION}")

After cmake .., I have the following warnings:

Then I try to make it: [@gpu build]$ make It gives me the following errors:

(The name "gpu" occasionally causes notifications in projects of which I didn't even know that they existed....)

Until the project owners give a more detailed answer: The line

set(OpenCV_LIBS "/cluster/6.2/opencv/2.4.10/lib/")

is certainly wrong. You're setting the OpenCV_LIBS variable to point to a directory. But this variable is supposed to be a list of library names. (Roughly something like cvFoo.lib cvBar.lib cvWhatever.lib - a list of library names).

These should be set properly when using the find script via the

find_package( OpenCV REQUIRED )

line that you commented out. I'm not a CMake expert and not familiar with OpenCV, so I can't point you to the right FindOpenCV.cmake file, but things like http://stackoverflow.com/questions/8711109/could-not-find-module-findopencv-cmake-error-in-configuration-process (pointing to https://github.com/opencv/opencv/tree/master/cmake ) or websearches for FindOpenCV.cmake might be a start...

@gpu Thanks for your help. I add set(OpenCV_LIBS "/cluster/6.2/opencv/2.4.10/lib/libopencv_core.so"), and it solved the error of FindOpenCV.cmake.

@RyanCV This is wrong, set (OpenCV_LIBS /cluster/6.2/opencv/2.4.10/lib/libopencv_core.so)
