[Insight-users] switching debug and release build of itk build

[Xavier Mellado Esteban]

   Dear Felix:

   I am sorry, but for me, it is difficult to figure out what happens 
with this information. The way you include ITK in your project, it is 
not the usual one. Let me explain how I would do this.

1) Building

   Uncompress ITK in any folder, for example: 
/home/felix/InsightToolkit-3-2-0

   cd /home/felix/InsightToolkit-3-2-0
   mkdir bin
   cd bin
   mkdir release
   mkdir debug

   (so you have /home/felix/InsightToolkit-3-2-0/bin/release and 
/home/felix/InsightToolkit-3-2-0/bin/debug)

   cd release
   ccmake ../..

   Set CMAKE_BUILD_TYPE to Release

   Configure, generate and compile.

   You can do the same with debug, go to 
/home/felix/InsightToolkit-3-2-0/bin/debug folder and set 
CMAKE_BUILD_TYPE to Debug. Configure, generate and compile.

   If you want to install it, I suggest you to install at "/opt" . If 
you go to the release folder "make install" will create 
/opt/InsightToolkit-3-2-0, rename it to 
/opt/InsightToolkit-3-2-0-Release and do the same with debug, in order 
to create /opt/InsightToolkit-3-2-0-Debug. If you want to be more 
elegant, you can also create soft links with:

   ln -s InsightToolkit-3-2-0-Release ITK
   ln -s InsightToolkit-3-2-0-Debug ITK-Debug

   This will create /opt/ITK (release mode) and /opt/ITK-Debug (debug 
mode), so you will be able to change ITK version only installing a new 
version and changing the soft link, other users will not notice that...

   Now ITK is compiled and installed.

2) Including ITK

   Go to your project CMakeLists.txt and add the following lines.

   FIND_PACKAGE(ITK)
   IF(ITK_FOUND)
      INCLUDE(${ITK_USE_FILE})
   ELSE(ITK_FOUND)
      MESSAGE(FATAL_ERROR "Please set ITK_DIR.")
   ENDIF(ITK_FOUND)

   This code, usually, will give you an error at project configuration, 
asking for ITK folder. Set ITK_DIR to /opt/ITK/lib/InsightToolkit

   If you only include UseITK.cmake you are missing ITKConfig.cmake that 
is the one that sets most of the settings needed for build something 
against ITK.

                            I hope this helps you:
                                                                    Xavi
