I want to include SDL2 and GLEW to my Cmake project
The scr files are in C:\libs\src and I createt all the libaries in CMAKE with PATH CMAKE_Install_PRÄFIX like in this documentation:
Download and install CMake ( https://cmake.org/ ) and Visual Studio Community Edition ( https://visualstudio.microsoft.com/de/ )
Create a directory libs or libraries (whatever suits you) where you install all your libraries. It is reasonable to have this on a low level as in the future you might want to add further libraries and use this folder also for other projects. The following explanations assume that you use C:/libs. If you want to use another directory, just adapt the directory the way you need it.
Add C:/libs and C:/libs/bin to the Environment Variable Path ( https://www.computerhope.com/issues/ch000549.htm ).
Create a subdirectory libs/src, copy all the libraries from cgAdvancedFramework/deps/ to this folder and extract them.
SDL2:
Open cmake-gui
Source code: C:/libs/src/SDL2-2.0.12
Binaries: C:/libs/src/SDL2-2.0.12/build
Add entry
Name: CMAKE_INSTALL_PREFIX
Type: PATH
Value: C:\libs
Ok
Configure
Accept creating build directory
Use default native compiler --> Finish

Open Project (this should start Visual Studio)
Visual Studio

right-click ALL_BUILD --> Build (if errors appear, here you might have done something wrong before)
right-click INSTALL --> Build (if errors appear, ...)
do the same for Solution Configuration: RelWithDebInfo (optional but recommended)
My Project is locatet C:\Users\Documents...\dvs\volren

Where is my mistake ?
It seems that you are on Windows, so why add MACOSX_BUNDLE in your add_executable ?
Also, are you sure GLEW_INCLUDE_DIRS, SDL2_INCLUDE_DIRS are the correct variable to use ? Did you check if they were populated ?

I've been searching for a solution to this problem for a long time to no avail.
I am trying to compile this simple program:
#include <iostream>
#include <Magick++.h>
#include <Magick++/Image.h>
using namespace std;
using namespace Magick;
int main(int argc,char **argv) {
InitializeMagick("D:\\Programming\\CPPProjects\\NoteScripts\\Dependencies\\magick\\include");
Image image;
// image.read("arch");
// image.write("test.png");
}
Upon building, I get the following error:
CMakeFiles\main.dir/objects.a(main.cpp.obj):main.cpp:(.text+0x1c): undefined reference to `Magick::InitializeMagick(char const*)'
CMakeFiles\main.dir/objects.a(main.cpp.obj):main.cpp:(.text+0x28): undefined reference to `Magick::Image::Image()'
CMakeFiles\main.dir/objects.a(main.cpp.obj):main.cpp:(.text+0x34): undefined reference to `Magick::Image::~Image()'
collect2.exe: error: ld returned 1 exit status
From what I can tell, this is a linker error but I have no idea where I am going wrong with linking the libs needed.
I installed ImageMagick on Windows 10 from the ImageMagick downloads page with this installer: ImageMagick-7.1.0-50-Q16-HDRI-x64-dll.exe
I then copied the lib files from the lib folder under the installation directory into my project and then copied the include folder under the installtion directory into my project.
Here is what the project hierarchy looks like (Source Directory is NoteScripts):
My CMakeLists.txt consists of:
cmake_minimum_required(VERSION 3.10)
set( CMAKE_CXX_COMPILER "C:/Program Files/mingw-w64/x86_64-8.1.0-posix-seh-rt_v6-rev0/mingw64/bin/g++.exe")
set( CMAKE_C_COMPILER "C:/Program Files/mingw-w64/x86_64-8.1.0-posix-seh-rt_v6-rev0/mingw64/bin/gcc.exe" )
# set the project name
project("Notes")
include_directories(D:/Programming/CPPProjects/NoteScripts/Dependencies/magick/include)
# add the executable
add_executable(main main.cpp)
target_link_libraries(main D:/Programming/CPPProjects/NoteScripts/Dependencies/magick/lib/CORE_RL_Magick++_.lib)
target_link_libraries(main D:/Programming/CPPProjects/NoteScripts/Dependencies/magick/lib/CORE_RL_MagickCore_.lib)
target_link_libraries(main D:/Programming/CPPProjects/NoteScripts/Dependencies/magick/lib/CORE_RL_MagickWand_.lib)
If I comment out lines 9 and 10 where InitializeMagick() is called and where Image image is declared, the program compiles without error. I'm also aware that the order of the static libs listed out matters but trying out multiple combinations has resulted in the same error. I have also verfied the dependency order by sifting through the original source code and the reference path is Magick++ -> MagickCore -> MagickWand.
I am relatively new to the process of adding external dependencies to my C++ projects so this is unfamiliar territory (coming from languages with clean package managers). Any help as to how to fix this issue is greatly appreciated!
The typical (and easiest) way of handling dependencies in CMake is using its find_package command:
find_package(ImageMagick REQUIRED COMPONENTS MagickCore MagickWand Magick++)
// ...
target_link_libraries(main ${ImageMagick_LIBRARIES})
This method is available for ImageMagick with your CMake version. I'm not familiar with CMake on Windows, but find_package by default searches a number of standard (system) locations for the package's files. Since you have a custom setup, it should also be possible to specify a nonstandard search prefix to the command. Additionally, you could download external dependencies in a portable way with the FetchContent commands.
First of all, it is a pain to setup this thing if you are a newbie like me.
Now to the steps to dynamically link imagemagick libs with your C app:
go to https://github.com/ImageMagick/ImageMagick-Windows and follow the instructions there (Install Visual Studio dependencies - Clone the dependencies - Build configure.exe- Build ImageMagick)
in the step Build configure.exe, when running configure.exe, keep the default option selected when asked about the output library type (keep it set to dynamic)
in the Build ImageMagick step, when you open VisualDynamicMT.sln in visual studio, before you start the build, select all the solutions in the project, and right-click -> properties -> General -> C Language Standard -> choose Default (Legacy MSVC). After that, click on the top-most solution that contains all the other 196 solutions, and build it. watch the console for errors, I didn't get any errors with the configuration above.
After the latter step, go the VisualMagick folder (created from steps before), and you will see lib folder and bin folder. You're done, your dlls are in bin and your .lib file are in bin folder. Note that these files will be corresponding to build or release environments depending on what you selected in visual studio at the build step.
How do you use imagemagick now in your project regardless if you have imagemagick app installed on your pc or not? Lets create a new project in vscode, call it demo.
Create this project structure:
inside src you will put your C code.
inside deps create ImageMagick/lib and ImageMagick/bin and ImageMagick/include
inside ImageMagick/include place the same include files you said you got in your question.
inside ImageMagick/lib place the .lib files you got from above
inside ImageMagick/bin place the .dll files you got from above
now add this to your CMakeLists.txt:
cmake_minimum_required(VERSION 3.23)
project(demo-app C)
set(CMAKE_CXX_STANDARD 23)
set(CMAKE_EXPORT_COMPILE_COMMANDS ON)
file(GLOB SOURCE_FILES src/*.c)
add_executable(demo ${SOURCE_FILES})
include_directories(src)
# ImageMagick
if(WIN32)
add_definitions( -DMAGICKCORE_QUANTUM_DEPTH=16 )
add_definitions( -DMAGICKCORE_HDRI_ENABLE=0 )
include_directories(deps/ImageMagick/include)
target_link_directories(demo PRIVATE deps/ImageMagick/lib)
file(GLOB IMAGEMAGICK_LIBS deps/ImageMagick/lib/*.lib)
target_link_libraries(demo
"${IMAGEMAGICK_LIBS}"
)
add_custom_command(TARGET demo POST_BUILD
COMMAND ${CMAKE_COMMAND} -E copy_directory
"${PROJECT_SOURCE_DIR}/deps/ImageMagick/bin"
$<TARGET_FILE_DIR:demo>)
endif()
(The add_custom_command will copy the dlls to your executables path after every build)
Now write some magick code in you src directory.
ctrl + shift + A -> CMake select kit -> choose the Visual Studio community 2022 release -amd64 or change to what fits you if it doesn't work
ctrl + shift + A -> CMake Clean Rebuild
ctrl + shift + A -> CMake run without debugging
I wrote a CMakeLists.txt for a project in C++, which uses OpenCV libraries. When I try to create the project using cmake, I get the next configuration problem:
CMake Error at CMakeLists.txt:15 (find_package):
Could not find module FindOpenCV.cmake or a configuration file for package
OpenCV.
Adjust CMAKE_MODULE_PATH to find FindOpenCV.cmake or set OpenCV_DIR to the
directory containing a CMake configuration file for OpenCV. The file will
have one of the following names:
OpenCVConfig.cmake
opencv-config.cmake
The fact is that I have an environment variable for the path which I use in Visual Studio with no problems. If I don't include OpenCV, then I can configure and generate with no problem, but I need to solve the problem. I don't understand why cmake cannot find the OpenCV path or how to fix it.
I also used the recommendations mentioned in this link:
FindOpenCV.cmake
Does anybody had this problem too?
The error you're seeing is that CMake cannot find a FindOpenCV.cmake file, because cmake doesn't include one out of the box. Therefore you need to find one and put it where cmake can find it:
You can find a good start here. If you're feeling adventurous you can also write your own.
Then add it somewhere in your project and adjust CMAKE_MODULE_PATH so that cmake can find it.
e.g., if you have
CMakeLists.txt
cmake-modules/FindOpenCV.cmake
Then you should do a
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} ${CMAKE_CURRENT_SOURCE_DIR}/cmake-modules)
In your CMakeLists.txt file before you do a find_package(OpenCV)
If you are on Linux, you just need to fill the OpenCV_DIR variable with the path of opencv (containing the OpenCVConfig.cmake file)
export OpenCV_DIR=<path_of_opencv>
apt-get install libopencv-dev
export OpenCV_DIR=/usr/share/OpenCV
the header of cpp file should contain:
#include
#include "opencv2/highgui/highgui.hpp"
#include
#include
not original cv.h
find / -name "OpenCVConfig.cmake"
export OpenCV_DIR=/path/found/above
I had this exact same problem. I fixed it by adding the following line to my FindOpenCV.cmake file. Put it anywhere at the top before the rest of the code.
set (OpenCV_DIR /home/cmake/opencv/compiled) #change the path to match your complied directory of opencv
Basically you are telling FindOpenCV.cmake where to find opencv files assuming the other compilation can find the FindOpenCV.cmake
I faced the same error. In my case this "OpenCVConfig.cmake" file is located in /usr/local/share/OpenCV. In CMakeLists.txt add the line
set(OpenCV_DIR /usr/local/share/OpenCV)
as suggested by the error message.
if you are on windows, you can add opencv path to OpenCV_DIR yourself.
(OpenCV_DIR is in the red region)
the path is like "D:/opencv244/build".
you can find file "OpenCVConfig.cmake" under the path.
Another possibility is to denote where you can find OpenCV_DIR in the CMakeLists.txt file. For example, the following cmake scripts work for me:
cmake_minimum_required(VERSION 2.8)
project(performance_test)
set(OpenCV_STATIC ON)
set(OpenCV_CUDA OFF)
set(OpenCV_DIR "${CMAKE_SOURCE_DIR}/../install")
find_package(OpenCV REQUIRED)
include_directories(${OpenCV_INCLUDE_DIRS})
link_directories(${OpenCV_LIB_DIR})
file(GLOB my_source_files ./src/*)
add_executable( performance_test ${my_source_files})
target_link_libraries(performance_test ${OpenCV_LIBS})
Just to remind that you should set OpenCV_STATIC and OpenCV_CUDA as well before you invoke OpenCVConfig.cmake. In my case the built library is static library that does not use CUDA.
On my Fedora machine, when I typed "make" I got an error saying it could not find "cv.h". I fixed this by modifying my "OpenCVConfig.cmake" file.
Before:
SET(OpenCV_INCLUDE_DIRS "${OpenCV_INSTALL_PATH}/include/opencv;${OpenCV_INSTALL_PATH}/include")
SET(OpenCV_LIB_DIR "${OpenCV_INSTALL_PATH}/lib64")
After:
SET(OpenCV_INCLUDE_DIRS "/usr/include/opencv;/usr/include/opencv2")
SET(OpenCV_LIB_DIR "/usr/lib64")
I am using Windows and get the same error message. I find another problem which is relevant.
I defined OpenCV_DIR in my path at the end of the line. However when I typed "path" in the command line, my OpenCV_DIR was not shown. I found because Windows probably has a limit on how long the path can be, it cut my OpenCV_DIR to be only part of what I defined. So I removed some other part of the path, now it works.
I had the same error, I use windows. I add "C:\opencv\build" (opencv folder) to path at the control pannel.
So, That's Ok!!
For me (on Ubuntu), I just run:
sudo apt-get install libopencv-dev
Followed #hugh-pearse 's and #leszek-hanusz 's answers, with a little tweak. I had installed opencv from ubuntu 12.10 repository (libopencv-)* and had the same problem. Couldn't solve it with export OpenCV_DIR=/usr/share/OpenCV/ (since my OpenCVConfig.cmake whas there). It was solved when I also changed some lines on the OpenCVConfig.cmake file:
# ======================================================
# Include directories to add to the user project:
# ======================================================
# Provide the include directories to the caller
#SET(OpenCV_INCLUDE_DIRS "${OpenCV_INSTALL_PATH}/include/opencv;${OpenCV_INSTALL_PATH}/include")
SET(OpenCV_INCLUDE_DIRS "/usr/include/opencv;/usr/include/opencv2")
INCLUDE_DIRECTORIES(${OpenCV_INCLUDE_DIRS})
# ======================================================
# Link directories to add to the user project:
# ======================================================
# Provide the libs directory anyway, it may be needed in some cases.
#SET(OpenCV_LIB_DIR "${OpenCV_INSTALL_PATH}/lib")
SET(OpenCV_LIB_DIR "/usr/lib")
LINK_DIRECTORIES(${OpenCV_LIB_DIR})
And that worked on my Ubuntu 12.10. Remember to add the target_link_libraries(yourprojectname ${OpenCV_LIBS}) in your CMakeLists.txt.
When you install the libraries in the c drive (windows). the CMakeLists.txt shoud be looking like below:
cmake_minimum_required(VERSION 3.0.0)
project(test_opencv VERSION 0.1.0)
include(CTest)
enable_testing()
find_package(OpenCV REQUIRED)
include_directories(${OpenCV_INCLUDE_DIRS})
add_executable(test_opencv main.cpp)
target_link_libraries(test_opencv ${OPENCV_LIBS})
set(CPACK_PROJECT_NAME ${PROJECT_NAME})
set(CPACK_PROJECT_VERSION ${PROJECT_VERSION})
include(CPack)
finding the package and include directories
when building the project in VS code. Run the visual studio code with admin rights as the OpenCV is installed inside C drive.
After hours of scouring the web and SO for a solution I'm at a standstill. Nothing has worked so far for me...
I'm on Windows, using CLion IDE which uses CMake. My goal is to correctly link SDL2 to my project and use it through #include "SDL.h" which is the correct way.
The format of my CMakeLists.txt file
Specifics regarding the directory where I should have put the MingW development library of SDL2
Any requirements regarding windows ENV variables that I might have to set.
My CMakeLists.txt looks like this:
cmake_minimum_required(VERSION 3.6)
project(sdl2Project)
set(CMAKE_CXX_STANDARD 11)
#This is where sdl2-config.cmake is located
set(CMAKE_PREFIX_PATH ${CMAKE_PREFIX_PATH} "C:/Users/MyUserName/CLibraries/SDL2-2.0.5/x86_64-w64-mingw32/lib/cmake/SDL2")
set(SOURCE_FILES main.cpp)
add_executable(sdl2Project ${SOURCE_FILES})
find_package(sdl2 REQUIRED)
target_include_directories(sdl2Project PUBLIC ${SDL2_INCLUDE_DIRS})
target_link_libraries(sdl2Project ${SDL2_LIBRARIES})
There is no FindSDL2.cmake file used.
The SDL2 library I downloaded from libsdl.org is located in:
C:/Users/MyUserName/CLibraries/SDL2-2.0.5/x86_64-w64-mingw32
I have no experience with CMake so I'm unable to truly understand where the problem stems from. What are the steps I need to take in order for it to find the library and link it correctly??
EDIT:
My Project structure is the following:
sdl2Project
cmake-build-debug
CMakeLists.txt
main.cpp
Looking in your FindSDL2.cmake, you need to provide an hint to CMake about where the library is installed. You could do this by setting an environment variable SDLDIR, but you shouldn't. General advice: you shouldn't use a CMake package that wasn't provided with the sources you're using.
Looking in sources of SDL2, root directory contains a file sdl2-config.cmake.in that should have been configured and installed in your install directory as sdl2-config.cmake: that's the package file you should use.
Am I right guessing the file C:/Users/MyUserName/CLibraries/SDL2-2.0.5/sdl2-config.cmake exists?
If yes, to allow CMake to find it, add your install directory to CMAKE_PREFIX_PATH, before calling find_package:
set(CMAKE_PREFIX_PATH
${CMAKE_PREFIX_PATH}
"C:/Users/MyUserName/CLibraries/SDL2-2.0.5"
)
find_package(sdl2 REQUIRED)
Note the use of "/" in the path instead of "\" which could be interpreted as escaping character. Quotes around the path are only necessary if the path contains whitespaces.
EDIT:
Moreover, you misused target_link_libraries with a wrong target: SDL2 which you don't build in your project, instead of sdl2Project.
You also used a wrong variable: SDL2_LIBRARY instead of SDL2_LIBRARIES; you can see the good variable name by looking in sdl2-config.cmake.
You may consider target_include_directories instead of include_directories, but again the variable name you used is wrong: SDL2_INCLUDE_DIR instead of SDL2_INCLUDE_DIRS.
Try:
target_include_directories(sdl2Project PUBLIC ${SDL2_INCLUDE_DIRS})
target_link_libraries(sdl2Project ${SDL2_LIBRARIES})
How to use Boost library in Clion with MinGW ? I have downloaded and unzipped boost_1_60_0.zip to C:\boost_1_60_0. What am I supposed to do now ? Do I have to install something ? Here is my CMakeLists.txt:
cmake_minimum_required(VERSION 3.3)
project(server_client)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -s -O3")
set(CMAKE_EXE_LINKER_FLAGS -static)
set(BOOST_ROOT "C:/boost_1_60_0")
set(BOOSTROOT "C:/boost_1_60_0")
find_package(Boost 1.60.0)
if(NOT Boost_FOUND)
message(FATAL_ERROR "Could not find boost!")
endif()
set(SOURCE_FILES chat_server.cpp)
add_executable(server_client ${SOURCE_FILES})
Can not find Boost:
I use MinGW distro by Stephan T. Lavavej with Boost libraries prebuilt.
In my cmaklist.txt I added this
set(Boost_INCLUDE_DIR c:/mingw/include/)
set(Boost_LIBRARY_DIR c:/mingw/lib/)
find_package(Boost COMPONENTS system filesystem REQUIRED)
include_directories(${Boost_INCLUDE_DIR})
This post help me get it going. How to include external library (boost) into CLion C++ project with CMake?
Here's example project for CLion that uses Boost's regex library. It references to this tutorial.
Goal: with CLion create .exe that process jayne.txt as shown in Boost's tutorial.
My example revolves around building Boost Library Binary with GCC, configuring project in CLion and using CMake. It's quite expressive, maybe even an overkill, but I believe you can adapt. On the other hand I'll try to make project itself as system independent as its possible.
Configuration:
OS: Windows 8.1
CLion: 2018.2.4
Boost: 1.68.0
compiler: GCC-6.3.0 (provided by MinGW)
MinGW was configured according to its instructions and JetBrains's suggestions. (I downloaded setup for MinGW 14/10/2018 if that matters.)
A word about tools structure
I decided to create following structure for Boost and things aroung it:
D:\
SDK\
boost\
boost_1_68_0\ # untouched Boost root
boost\
rst.css
...other directories and files...
1_68_0\
build\ # dir for Boost.Build, b2.exe
buildDir\ # intermediate dir for creating libraries
stageDir\ # dir for libraries
lib\
MinGW\
bin\
...other directories...
I left Boost root untouched -- I didn't create any additional directories. This separates Boost sources from created tools and libraries so I can show how to specify these directories explicitly.
Obtain Boost Library Binary
I decided to build libraries from source with GCC.
Download and unpack Boost ("D:\SDK\boost\boost_1_68_0");
Build libraries (5.2):
Open command prompt at \tools\build of Boost root ("D:\SDK\boost\boost_1_68_0\tools\build")
Run bootstrap.bat
Run b2 install --prefix="D:\SDK\boost\1_68_0\build" --toolset=gcc-6.3.0. This creates b2.exe under "D:\SDK\boost\1_68_0\build\bin"
Move command prompt to Boost root (cd "D:\SDK\boost\boost_1_68_0")
(You can consider using "D:\SDK\boost\1_68_0\build\bin\b2.exe --show-directories". It's worth to specify libraries to build (--with-library-name) in the following command, because this step can take a while.) Run "D:\SDK\boost\1_68_0\build\bin\b2" --build-dir="D:\SDK\boost\1_68_0\buildDir" toolset=gcc-6.3.0 --build-type=complete stage --stagedir="D:\SDK\boost\1_68_0\stageDir" --with-regex. It creates following files under D:\SDK\boost\1_68_0\stageDir\lib directory:
libboost_regex-mgw63-mt-d-x32-1_68.a
libboost_regex-mgw63-mt-d-x32-1_68.dll
libboost_regex-mgw63-mt-d-x32-1_68.dll.a
libboost_regex-mgw63-mt-sd-x32-1_68.a
libboost_regex-mgw63-mt-s-x32-1_68.a
libboost_regex-mgw63-mt-x32-1_68.a
libboost_regex-mgw63-mt-x32-1_68.dll
libboost_regex-mgw63-mt-x32-1_68.dll.a
CMake looks for files with specific names in library folder, so be sure to (copy and) change name for one of .a files there. For this example, I changed libboost_regex-mgw63-mt-x32-1_68.a to boost_regex.a.
Create CLion project
Create a new project (for this example its name is CLionBoostRegex) and put content to main.cpp (6):
#include <boost/regex.hpp>
#include <iostream>
#include <string>
int main()
{
std::string line;
boost::regex pat( "^Subject: (Re: |Aw: )*(.*)" );
while (std::cin)
{
std::getline(std::cin, line);
boost::smatch matches;
if (boost::regex_match(line, matches, pat))
std::cout << matches[2] << std::endl;
}
}
Configure CLion
Go to (on Windows) File -> Settings -> Build, Execution, Deployment -> CMake, and in CMake options add path to Boost root directory with -DBOOST_ROOT=, i.e.: -DBOOST_ROOT="D:\SDK\boost\boost_1_68_0". If directory with built libraries is placed outside Boost root, add it with -DBOOST_LIBRARYDIR=, i.e.: -DBOOST_LIBRARYDIR="D:\SDK\boost\1_68_0\stageDir\lib". Commands are space separated.
Decide if you want static or dynamic linking.
Option 1: Static linking
For static linking your CMakeLists.txt should look like this:
cmake_minimum_required(VERSION 3.12)
project(CLionBoostRegex)
set(CMAKE_CXX_STANDARD 98)
find_package(Boost REQUIRED COMPONENTS regex)
include_directories(${Boost_INCLUDE_DIRS})
add_executable(CLionBoostRegex main.cpp)
target_link_libraries(CLionBoostRegex -static)
target_link_libraries(CLionBoostRegex ${Boost_LIBRARIES})
Option 2: Dynamic linking
CMakeLists.txt should look like for static linking, but remove target_link_libraries(CLionBoostRegex -static) line.
After building your project make sure to copy .dll library to directory with executable (libboost_regex-mgw63-mt-x32-1_68.dll) along with libstdc++-6.dll from MinGW\bin directory (D:\SDK\MinGW\bin) (or consider including target_link_libraries(CLionBoostRegex -static-libstdc++) line in CMakeLists.txt or add -DCMAKE_CXX_FLAGS="-static-libstdc++" to CMake options in settings).
Run your program (6.4)
Build your target (it creates cmake-build-debug\ directory with default config) (if you picked dynamic linking make sure to add necessary .dlls)
In directory with your executable create jayne.txt file with following content:
To: George Shmidlap
From: Rita Marlowe
Subject: Will Success Spoil Rock Hunter?
---
See subject.
Open command prompt there
Run CLionBoostRegex.exe < jayne.txt
Program should output Will Success Spoil Rock Hunter? as shown in tutorial.
Notes
Changing name for an .a library and choosing -static linking causes the least effort afterwards - you won't have to copy any additional libraries at the price of bigger executable size. When executable size is more important, you can change name for .dll library in Boost libraries directory instead and then copy missing .dlls for your .exe (i.e.: libboost_regex-mgw63-mt-x32-1_68.dll and libstdc++-6.dll).
You can include set(Boost_DEBUG ON) line in your CMakeLists.txt or -DBoost_DEBUG=1 to CMake options to get some precious info.
I used other questions to write this post, most notably: 1, 2, 3, 4.
I am new to ITK and I did the following step to install ITK and use it to programme in VS2010
Downloaded ITK 4.3.1 and build it with CMAKE
The build was successful and I had a lib->Debug folder containing the libs.
Added the bin folder path to environmental vairable path.
Following is my simple code...
#include <iostream>
#include <Core/Common/include/itkImage.h>
using namespace itk;
using namespace std;
int main()
{
return 0;
}
the above code returns
Cannot open include file: 'itkConfigure.h'
I tried searching for that header but no luck. However in C:\InsightToolkit-4.3.1\Modules\Core\Common\src I found itkConfigure.h.in file. I am really clueless about how to go about this .in file. Any help is most welcome..
The easiest way to set up your project is to use CMake again. Try creating a project with just a CMakeLists.txt and main.cpp. The CMakeLists.txt should have something like:
cmake_minimum_required(VERSION 2.8 FATAL_ERROR)
project(ItkTest)
find_package(ITK REQUIRED)
include(${ITK_USE_FILE})
add_executable(MyTest main.cpp)
target_link_libraries(MyTest ITKCommon)
So say you create these 2 files in a dir called ItkProject, then from a Visual Studio Command Prompt just do:
cd <path to ItkProject>
mkdir build
cd build
cmake .. -DITK_DIR="<path to build dir of ITK>"
The <path to build dir of ITK> is where you ran CMake from to configure the ITK project. It will contain the ITK.sln file, but critically it should also contain a file called ITKConfig.cmake. It is this file which is searched for in the cmake command find_package(ITK REQUIRED) - if CMake can't find it the configuring will fail.
Once that's been found, it sets a bunch of CMake variables which you can then use in your own CMakeLists.txt, including ITK_USE_FILE.
When you then invoke include(${ITK_USE_FILE}), this goes on to set up things like your includes paths, library search paths, and compiler flags. The path <path to ItkProject>/Core/Common/include will be added to the includes dirs, so in your main.cpp, you just need to do:
#include <Core/Common/include/itkImage.h>
#include "itkImage.h"
Anyway, the end result after running CMake should be solution file <path to ItkProject>\build\ItkTest.sln which is set up ready to use ITK.
I checked \ItkConfig.cmake and paths defined there should match physical paths, this is the case if ITK build has been untouched (directory wasn't renamed).
# The ITK source tree.
# For backward compatibility issues we still need to define this variable, although
# it is highly probable that it will cause more harm than being useful.
# Use ITK_INCLUDE_DIRS instead, since ITK_SOURCE_DIR may point to non-existent directory
