Cmake compile all c++ files in directory with VTK dependency

Question

I have a main file and two classes in C++, all of which use VTK libraries.

I know how to compile one file, how should my CMakeLists look like to compile them all?

Example of the code:

Main:

#include <vtkImageData.h> #include <vtkMetaImageReader.h> #include <vtkSmartPointer.h> #include "ClassA.h" #include "ClassB.h"

ClassA.cpp:

#include "ClassA.h"

ClassB.cpp:

#include "ClassB.h"

ClassA.h:

#include <vector> #include "vtkImageData.h"

ClassB.h:

#include <vector> #include <string> #include <sstream> #include "vtkImageData.h" #include "vtkMetaImageWriter.h"

Your CMakeLists.txt could look like this:

cmake_minimum_required(VERSION 2.8) PROJECT(MyProject) find_package(VTK REQUIRED) include(${VTK_USE_FILE}) add_executable(MyExecutable main.cpp ClassA.cpp ClassB.cpp) target_link_libraries(MyExecutable ${VTK_LIBRARIES})
