[Insight-users] Using compiled ITK libraries

[Michael Jackson]

No, you do not have to include all the ITK Source code. Here are the  
quick steps.

Build and Install ITK. MacPorts, Fink or By Hand. Make a note of the  
installation directory.

You can now just create an Xcode project and reference the needed itk  
libraries in your Xcode project. You will also have to manually setup  
all the necessary include directories for your project.

The _better_ way would be to use CMake to manage your project. You can  
look in the ITK examples directory for examples on how to write a  
CMakeLists.txt file. I personally suggest the following:

Create a project directory "itkTest'
  Within the itkTest directory create a text file called  
'CMakeLists.txt'
  Write the necessary Cmake code, save the file.

#--------- Begin CMakeLists.txt -----------
project(itkTest)

# --------------------------------------------------------------------
# Find the ITK Package
# --------------------------------------------------------------------
FIND_PACKAGE(ITK)
IF(ITK_FOUND)
   INCLUDE(${USE_ITK_FILE})
ELSE(ITK_FOUND)
   MESSAGE(FATAL_ERROR "Cannot build without ITK.  Please set ITK_DIR.")
ENDIF(ITK_FOUND)

add_executable(itkTest itkTest.cpp)
target_link_libraries(itkTest ${ITK_LIBRARIES})
#----------- End CMakeLists.txt -------------------

Write your program in the itkTest.cpp file


Next step is to generate the Xcode project. The easiest way is to open  
the "terminal.app" and navigate to the project directory. So say you  
created your project on the Desktop, then in the terminal execute the  
following commands:

cd ~/Desktop/itkTest
mkdir Build
cd Build
cmake -G Xcode ../
open itkTest.xcodeproj

At that point Xcode should launch with a brand new Xcode project ready  
to go. Try to compile and run your program.

Good Luck
