Have you tried specifying the version?
FIND_PACKAGE(OpenCV 2.2.0 EXACT REQUIRED)
FIND_PACKAGE(OpenCV 2.4.0 EXACT REQUIRED)
Not sure if the FindOpenCV script can handle the version argument.

Hello list,
To compile and link my code with the OpenCV library, I use
find_package( OpenCV REQUIRED )
...
add_executable(framecountertest framecountertest.cpp)
target_link_libraries(framecountertest ${OpenCV_LIBS})
and this works just fine: the OpenCV library that got installed using my
package management system
on Ubuntu 12.10 is being used.
However, under the directory /tmp/opencv_install I have another manual
installation of a more recent
OpenCV library, and I would like to use that one instead of the default on my
system, or easily
switch between the two versions. How should I specify that in my
CMakeLists.txt file? I have tried
set(OpenCV_FOUND "1")
set(OpenCV_INCLUDE_DIR "/home/bart/Git/Research/fat/inc/TraficonOpenCv/opencv")
set(OpenCV_LIBS
"opencv_gpu;opencv_contrib;opencv_legacy;opencv_objdetect;opencv_calib3d;opencv_features2d;opencv_video;opencv_highgui;opencv_ml;opencv_imgproc;opencv_flann;opencv_core")
include_directories(${OpenCV_INCLUDE_DIR})
...
add_executable(framecountertest framecountertest.cpp)
target_link_libraries(framecountertest ${OpenCV_LIBS})
but even with these commands, still the default libs on my system are being
used...
What is the correct way to specify that I want to build with the install under
/tmp/opencv_install
? And how can I easily switch between versions without needing to remove one
or the other version?
Thanks!
Bart
