So I'm trying to use OpenCV on windows (my ubunut is broken) and I can't configure my Clion to compile my openCV code.
first; i'm completely new to OpenCV so this question might be an easy one but I did all I could to find the problem to no avail.
I used MinGW and Clion and my codes run with no problem if I don't use OpenCv which indicates there's no problem with MinGW installation.
I downloaded OpenCv files and extracted them, then added them to System path.
after that I configured my Cmakelists.txt (my first time modifying it, so I was an amateur) like this.
After that I got this error:
Error:By not providing "FindOpenCV.cmake" in CMAKE_MODULE_PATH this
project has asked CMake to find a package configuration file provided
by "OpenCV", but CMake did not find one. Could not find a package
configuration file provided by "OpenCV" with any of the following
names: OpenCVConfig.cmake opencv-config.cmake Add the installation
prefix of "OpenCV" to CMAKE_PREFIX_PATH or set "OpenCV_DIR" to a
directory containing one of the above files. If "OpenCV" provides a
separate development package or SDK, be sure it has been installed.
I know I'm doing something wrong or missing a step but I can't figure out why. is there any guide or tutorial for my scenario or can anyone point me towards a correct direction?
thanks in advance and any help appreciated.
I managed to make those errors go away with changing my
CMakeLists.txt to:
cmake_minimum_required(VERSION 3.5)
project(something)
set(OpenCV_DIR "E:/Programs/programming/opencv/build2") find_package( OpenCV REQUIRED )
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(SOURCE_FILES main.cpp) add_executable(something ${SOURCE_FILES})
add_executable( {SOURCE_FILES} DisplayImage ) target_link_libraries( ${OpenCV_LIBS} DisplayImage )
and building the libraries on my own by minGW and Cmake.

I've been stuck for a while now and I can't figure out how to get freeglut working. I thought I knew what it was asking me to do, so I added that set(prefix_path) line but it didn't do anything. Am I supposed to write my own freeglut-config.cmake or what?
Note: I am using the freeglut for MinGW package from this website
CMake File:
cmake_minimum_required(VERSION 3.7)
project(HW1)
set(CMAKE_CXX_STANDARD 11)

If your application is GLUT-compatible, that it doesn't use any extension of freeglut, then it is better to search GLUT instead of FREEGLUT:
find_package(GLUT REQUIRED)
"Find" script used by this command is already shipped into CMake distro, and it searches freeglut too.
(Note, that with that command variables for include directories and linking libraries are GLUT_INCLUDE_DIR and GLUT_LIBRARY correspondingly).
If your application requires exactly freeglut (that is, uses some of its extensions incompatible with other GLUT implementations), you need to ship your package with FindFREEGLUT.cmake script and adjust CMAKE_MODULE_PATH variable correspondingly:
# Assuming you have <source-dir>/cmake/FindFREEGLUT.cmake
list(APPEND CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/cmake")
find_package(FREEGLUT REQUIRED)
You may find existing script in the net, or write it by yourself, like here.
In any case, if you have freeglut installed into non-system location, you need to hint CMake about that. E.g., by adjusting CMAKE_PREFIX_PATH.
I'm very new to CLion, CMake and macOS at all so I need a little bit of help while trying to include cppnetlib into my CLion project.
I started out with creating an new CLion project which gave me a new CMakeLists.txt which I edited so that it would include boost as well:
CMAKE_MINIMUM_REQUIRED(VERSION 3.7)
PROJECT(myapp)
SET(CMAKE_CXX_STANDARD 11)
SET(SOURCE_FILES main.cpp)
ADD_EXECUTABLE(myapp ${SOURCE_FILES})
FIND_PACKAGE(Boost 1.63.0 REQUIRED)
INCLUDE_DIRECTORIES(${Boost_INCLUDE_DIR})
TARGET_LINK_LIBRARIES(dxcheck ${Boost_LIBRARIES})
I've installed boost through homebrew, but I did not find a package for cppnetlib with homebrew so I downloaded cppnetlib and placed it in /usr/local/Cellar/cpp-netlib. Now, when I follow the tutorial on their page and put
set (CMAKE_PREFIX_PATH ${CMAKE_PREFIX_PATH} /usr/local/Cellar/cpp-netlib)
find_package (cppnetlib 0.12.0 REQUIRED)
include_directories (${CPPNETLIB_INCLUDE_DIRS})
target_link_libraries (myapp ${CPPNETLIB_LIBRARIES})
into the CMakeLists.txt, I get the following output:
-- Boost version: 1.63.0
CMake Error at CMakeLists.txt:14 (find_package):
By not providing "Findcppnetlib.cmake" in CMAKE_MODULE_PATH this project

(requested version 0.11.0) with any of the following names:

"cppnetlib_DIR" to a directory containing one of the above files. If
"cppnetlib" provides a separate development package or SDK, be sure it has

I've already done some research about finding packages but all I could achieve was that I was able to include cppnetlib by manually adding the include path to the CMakeLists.txt but then I got an error saying that the compiler could not find the headers which are located inside the "deps" folder in cpp-netlib.
I know want to know how to include a package like cppnetlib properly into my CLion project using CMake. I am using CLion 2017.1, macOS Sierra and I think CLion is using CMake 3.7.
i'm trying to use SFML's library with CLion for a school project. I'm still not confident with programming and i am new to Clion.
After having download the library from SFML official site i read some tutorials, but i am a bit confused:
https://www.sfml-dev.org/tutorials/2.4/
Infact in the Getting Started section there are two voice that concern me: "Compiling with Cmake" and "..Code::Blocks (MinGW).
Well i tryed both but with no results, then i landed here.
I saw a topic that helped a bit configure SFML for clion (windows)
so i tried to follow the steps suggested.
The library is in C:\SFML-2.4.2
I copied FindSFML.cmake in SFMLProjects, located in C:\Users\Ludovico\ (the same path of the folder ClionProjects)
Then i gave it a try
cmake_minimum_required(VERSION 3.6)
project(provaSfml)
set(CMAKE_CXX_STANDARD 11)
set(SOURCE_FILES main.cpp)
add_executable(provaSfml ${SOURCE_FILES})
set(CMAKE_MODULE_PATH "${CMAKE_CURRENT_LIST_DIR}/SFMLProjects")
link_directories(C:/SFML-2.4.2/bin)
find_package(SFML REQUIRED system window graphics network audio)
if (SFML_FOUND)
include_directories(${SFML_INCLUDE_DIR})
target_link_libraries(provaSfml ${SFML_LIBRARIES})
endif ()
These are the error messages

I'm thinking i did some mistakes even in the organization of folder...
can someone tell me some advice in order to clean the mess i have in my head?
What can i do to fix these problems?
How can I link shared object to my own code in cmake ?
I'd like to link OpenCV, I mean libopencv_***.so.3.1 or something like that to my own software package.
In that case, I believe the following lines are the answer of this question.
...
find_package(OpenCV 3.1)
include_directories(${OpenCV_INCLUDE_DIRS})
link_directories(${OpenCV_LIBRARY_DIRS})
...
target_link_libraries(my_node ${OpenCV_LIBRARIES})
But, here's this problem.
I've installed OpenCV 2.4.8 under /usr/include and /usr/lib/x86_64-linux-gnu before, and now I'd like to use OpenCV 3.1.0 installed in local directory "~/Libs/opencv" from code.
So when compiling the codes, OpenCV 2.4.8 takes priority and is used.
In this case, how should I describe CMakeLists.txt ?
Currently I'm writing as the follow.
...
set(CMAKE_PREFIX_PATH ${HOME}/Libs/opencv)
include(${HOME}/Libs/opencv/share/OpenCV/OpenCVConfig.cmake)
find_package(OpenCV 3.1)
set(OpenCV_INCLUDE_DIRS ${HOME}/Libs/opencv/include)
include_directories(${OpenCV_INCLUDE_DIRS)
set(OpenCV_LIBRARY_DIRS ${HOME}/Libs/opencv/lib)
link_directories(${OpenCV_LIBRARY_DIRS})
...
The above CMakeLists.txt kind of helped me.
If executable file is copied to the same directory where libopencv_***.so.3.1 is, the above CMakeLists.txt works.
Otherwise, "make" fails.
But I'd like to make it independent on the directory which contains executable file.
How should I do for this problem ?
Thanks in advance.
See cmake's doc of find_library.
Some predefined paths are used to search for libs. (Platform dependent). It is possible to disable this by options.
Try
find_package(OpenCV 3.1 PATHS ~/Libs/opencv NO_DEFAULT_PATH NO_SYSTEM_ENVIRONMENT_PATH)
I have little problem with my ROS hydro distro. I need to use it for one project so can't change to Indiko.
Problem is that I have used catkin_create_pkg packname opencv2 ... for creating my project package. But when I try to invoke catkin_make I get following errors:
CMake Error at /opt/ros/hydro/share/catkin/cmake/catkinConfig.cmake:75
(find_package): Could not find a package configuration file provided
by "opencv2" with any of the following names:
opencv2Config.cmake
opencv2-config.cmake
Add the installation prefix of "opencv2" to CMAKE_PREFIX_PATH or set
"opencv2_DIR" to a directory containing one of the above files. If
"opencv2" provides a separate development package or SDK, be sure it
has been installed.
I know that opencv2 is installed, because I can find it with rospack find opencv2 and I can use it in other projects not related to ROS.
I have following lines in CMakeLists.txt and package.xml
CMakeLists.txt:
find_package(catkin REQUIRED COMPONENTS opencv2)
include_directories(
${catkin_INCLUDE_DIRS}
${opencv2_INCLUDE_DIRS} )
target_link_libraries(BasicObstDetect_node
${catkin_LIBRARIES}
${opencv2_LIBRARIES} )
package.xml:
<build_depend>opencv2</build_depend>
<run_depend>opencv2</run_depend>
I have tried to use OpenCV instead of opencv2 but that didn't make any difference. Any advices?
I'm not sure, but this might work: edit your CMakeLists to add
find_package(OpenCV)
include_directories(${OpenCV_INCLUDE_DIRS})
and
target_link_libraries(follower ${OpenCV_LIBRARIES})
