I'm begining an opencv project in C++ and I figure that it'll be a nice occasion to learn some cmake. This is my project hirerachy:
project/
|__include/
|__sample1.h
|__sample2.h
|__build/
|__doc/
|__src/
|__sample1.cpp
|__sample2.cpp
|__test/
|__main.cpp
|__CMakeLists.txt
The CMakeLists.txt is :
CMAKE_MINIMUM_REQUIRED( VERSION 2.8 )
SET( PROJ_NAME "Project" )
SET( PROJ_PATH ${CMAKE_SOURCE_DIR} )
SET( PROJ_OUT_PATH ${CMAKE_BINARY_DIR} )
SET( PROJ_LIBRARIES ${OpenCV_LIBS} )
SET( PROJ_INCLUDES "include" )
FILE( GLOB_RECURSE PROJ_SOURCES src/*cpp test/*cpp )
FILE( GLOB_RECURSE PROJ_HEADERS include/${PROJ_NAME}/*.h )
PROJECT( ${PROJ_NAME} )
FIND_PACKAGE( OpenCV REQUIRED )
INCLUDE_DIRECTORIES( ${PROJ_INCLUDES} )
ADD_EXECUTABLE( ${PROJ_NAME} ${PROJ_SOURCES} )
TARGET_LINK_LIBRARIES( ${PROJ_NAME} ${PROJ_LIBRARIES} )
The makefile is generated, but when I execute "make" I have some "undefined references" to opencv functions.
Any help would be appreciated, and of course if you want more information just ask :)
Thanks
SET( PROJ_LIBRARIES ${OpenCV_LIBS} )
OpenCV_LIBS will be set AFTER you search for the package with find_package().
You also need to add your headers to add_executable().

I am trying to use cspice with g++ for windows via mingw. Unfortunately cspice does not provide a library for mingw. The libraries are available at https://naif.jpl.nasa.gov/naif/toolkit_C.html.
It gives undefined reference errors for the functions defined through cspice. It runs properly in Linux.
Can anyone suggest a method to make it work.
I run:
g++ -LK:\Data\cspice\lib -IF:\CPP\Libraries\Boost\boost_1_68_0 -o foo foo.cpp -l:cspice.a -lm
The errors I get are:
undefined reference to 'furnsh_c'
and other functions I use from 'SpiceUsr.h'.
Am I not linking the file properly or what is the error.
I managed to compile this in windows using MinGW.
I downloaded the code from NASA website for UNIX not WINDOWS.
You need to download a libf2c library, the arith.h (comment this line //#include <config.h>) header and the times.h header.
Then I use the following CMakeLists.txt with MinGW and CMAKE for windows.
mkdir build
cd build
cmake .. -G "MinGW Makefiles"
mingw32-make
Some compilation errors will came out but they are very straightforward to solve.

I am fairly new to CMake and using C++ Frameworks and have trouble setting up my project. When I try to build it I get the following error
/Users/adjust/Documents/C++/WebService/main.cpp:7:10: fatal error: 'restbed' file not found
I cloned the restbed repo into my project folder WebService. The Build was no problem, in restbed.build make test succeeded to 100%.
Troubleshooting the issue did not lead to success (yet) so I hope that maybe with a solution to my answer other newbies might be helped in the future as well.
I am using CLion on OS X and my CMakeList.txt file as followed.

I understood that I need only the library and include of the distribution folder. What am I doing wrong?

#add_executable(WebService ${SOURCE_FILES})
add_executable(WebService main.cpp)
target_link_libraries(WebService ${restbed_LIBRARY_FILES})
so, i'm trying to compile my program which has restbed as dependency.
I already compiled restbed with the following command:
cmake -DBUILD_TESTS=NO -DBUILD_SSL=YES -DBUILD_SHARED=NO
make -j4 install
Compiling restbed does not result in any errors.
Now the Problem:
I'm using the example source code from here: https://github.com/Corvusoft/restbed
This is my CMakeLists:
cmake_minimum_required (VERSION 2.6)
project(FDRService CXX)
# Setup
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(CMAKE_BINARY_DIR "./build")
set(EXECUTABLE_OUTPUT_PATH ${CMAKE_BINARY_DIR})
set(LIBRARY_OUTPUT_PATH ${CMAKE_BINARY_DIR})
# FD Variables
set(FDRService_VERSION_MAJOR 1)
set(FDRService_VERSION_MINOR 0)
set(FDRService_INCLUDE_DIR "./include")
set(FDRService_SOURCE_DIR "./src")
# RestBED
set(RESTBED_ROOT "dependency/restbed/distribution")
set(RESTBED_INCLUDE_DIR "${RESTBED_ROOT}/include")
set(RESTBED_LIBRARY_DIR "${RESTBED_ROOT}/library")
# find all libraries
file(GLOB_RECURSE RESTBED_LIBRARY_FILES
"${RESTBED_LIBRARY_DIR}/*.a"
)
include_directories(${RESTBED_INCLUDE_DIR})
# find project source files
file(GLOB_RECURSE FDRService_FILES
"${FDRService_INCLUDE_DIR}/*.h"
"${FDRService_INCLUDE_DIR}/*.hpp"
"${FDRService_SOURCE_DIR}/*.c"
"${FDRService_SOURCE_DIR}/*.cpp"
)
add_executable(FDRService ${FDRService_FILES})
target_link_libraries(FDRService ${RESTBED_LIBRARY_FILES})
When i try to compile my project i get the following linker errors:
http://pastebin.com/hXPmAV2W (too much text for StackOverflow...)
My guess is that the OpenSSL library is not linked into the static .a file of restbed, but i put -DBUILD_SSL in the build command.
I hope anyone of you can help me with this problem. It's driving me crazy.
If you need more information, just tell me and i'll edit this post.

The proper filename extension for libraries varies on different platforms. While .lib is used for both static and dll import libraries on Windows, OS X uses different naming conventions (.a for static and .so/.dylib for dynamic libraries, possibly with a lib prefix).
In order to still allow code that works with all those different naming conventions, find_library expects you to omit any extensions or prefixes completely and just give the bare name of the library.
So instead of find_library(SDL2 NAMES SDL2.lib [...]) you should just write find_library(SDL2 NAMES SDL2 [...]).
From your question it also seems that you are trying to link your OS X build against Windows binaries (.lib and .dll file extensions). This will not work. You need a separate set of binaries compiled for OS X.
Now I am using CMake to create a VC 10 project. One issue I have found is that the path of the output library or execute program is connected with the project configuration (debug or release). In order to illustrate it, I give the following examples:
cmake_minimum_required( VERSION 2.6 )
project (test)
add_definitions (-DEXP_STL )
add_library(lib1 SHARED lib1.cxx)
set_target_properties(lib1 PROPERTIES LINK_INTERFACE_LIBRARIES "")
set(LIBRARY_OUTPUT_PATH ${test_SOURCE_DIR})
The last command in the script denote that I would like to put the output library (lib1) in the directory of ${test_SOURCE_DIR}. However, the output library is located in ${test_SOURCE_DIR}/Debug instead. I was wondering how I could make sure that the output library is exactly in the path I have set. Thanks!
BWT: The reason why I raise this question is because in the Linux development environmental the output library or execute program path is exactly the path you set with set(LIBRARY_OUTPUT_PATH ...) function. I want to have a consistent result.
This question is regarded as duplicated, and one possible solution is as follows:
if (WIN32)
set(myoutputdirectory ${your_source_file_SOURCE_DIR}/output/win/32)
elseif (CMAKE_COMPILER_IS_GNUCC)
set(myoutputdirectory ${your_source_file_SOURCE_DIR}/output/linux/32)
elseif(APPLE)
set(myoutputdirectory ${your_source_file_SOURCE_DIR}/output/mac/32)
endif (WIN32)
# set output parth
set( CMAKE_RUNTIME_OUTPUT_DIRECTORY ${myoutputdirectory} )
set( CMAKE_LIBRARY_OUTPUT_DIRECTORY ${myoutputdirectory} )
set( CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${myoutputdirectory} )
# for multi-config builds (e.g. msvc)
foreach( OUTPUTCONFIG ${CMAKE_CONFIGURATION_TYPES} )
string( TOUPPER ${OUTPUTCONFIG} OUTPUTCONFIG )
set( CMAKE_RUNTIME_OUTPUT_DIRECTORY_${OUTPUTCONFIG} ${myoutputdirectory} )
set( CMAKE_LIBRARY_OUTPUT_DIRECTORY_${OUTPUTCONFIG} ${myoutputdirectory} )
