[Insight-users] cmake couldn't find ITK-4.0

Thu May 26 13:55:56 EDT 2011

Hi Juan,

With today's version of ITKv4.

When you install it you get subdirectories

* bin
* include
* lib
* share

For example,
I'm installing it in

           /home/ibanez/local/itk

so, I have

/home/ibanez/local/itk/bin
/home/ibanez/local/itk/include
/home/ibanez/local/itk/lib
/home/ibanez/local/itk/share

The files ITKConfig.cmake and UseITK.cmake
are in this case, in the directory

/home/ibanez/local/itk/lib/cmake/ITK-4.0

as

/home/ibanez/local/itk/lib/cmake/ITK-4.0/ITKConfig.cmake
/home/ibanez/local/itk/lib/cmake/ITK-4.0/UseITK.cmake

The headers are of course installed in

/home/ibanez/local/itk/include/ITK-4.0

and the libraries are of course installed in

/home/ibanez/local/itk/lib

The libraries have been names with the version number
(4.0) on purpose, to make possible for you to have multiple
versions of ITK installed without having conflicts between
them.

-----

      Here is the important thing to keep in mind:

When you configure with CMake your ITK-based project,
in the ITK_DIR entry you must put the directory where
UseITK.cmake is located.

In my case:

ITK_DIR:PATH=/home/ibanez/local/itk/lib/cmake/ITK-4.0

With that setting, CMake knows that it can find the headers in

/home/ibanez/local/itk/include

and the libraries in

/home/ibanez/local/itk/lib

       Luis
