Hi guys,

I have installed ros kinetic on my TX2 and it comes with opencv 3.3.1 which is not build with CUDA options so in parallel i have built from source the latest opencv (3.4.2) and in my CMakeLists i added the following option for the find package.

find_package(OpenCV 3.4.2 REQUIRED
PATHS /usr/local /usr
message("OpenCV version: ${OpenCV_VERSION}")

During the catkin_make, i got the correct version of opencv But in my c++ code, when i check the version of opencv with a simple std::cout, the code gives me version of ROS. how can i be sure which one is really used? Thank you in advance.


The cmakLists and the catkin_make use the correct version of opencv but when i run my node, it used the ros one. Should i build from source all packages which use opencv by checking their cmakelists and modify to fit my version number?

PS: i need the opencv build for CUDA.

This, #q301328 and #q301331 all seem at least related, but could also be duplicates. It's hard to tell.

Could you check and close the ones that are in fact duplicates of this question?
