How to disable particular default module

I would like disable some default modules, specially GDCM / GDCMIO, in my application i use own stuff for DICOM and also GDCM-clone library, so i don’t need the module.
Is it possible with some command line argument? Tried in cmake-gui, but it was somewhat complicated, many click are required, i need this for 4 builds.

Hi Mihail,

You have to first disable ITK_BUILD_DEFAULT_MODULES. Then you will see the modules and groups that you can enable or disable based on your needs.

You can also enable ITK_USE_SYSTEM_GDCM and other ITK_USE_SYSTEM_* options and provide path to your versions of those libraries.

Thanks, i used ITK_USE_SYSTEM_GDCM earlier, don’t want, i use another DICOM IO. I am surprised how difficult is to get rid of it. In the past, in earlier v4 versions it was possible, i remember, there were options, now there is no option, even if “default modules off” is set, now it is not a module, it is hard-coded as dependency, mostly for testing stuff. Could remove only with destructive editing.

It is a module. Have you tried setting the CMake options (in the terminal):

or maybe you just want to get rid off the IO with the second option.

If you have your own clone/version of GDCM, you can point to that one with the ITK_USE_SYSTEM_GDCM and then disable the IO module if not interested.

Hope it helps

GDCM might be requested by one of its dependencies. When configuring ITK, there is a list of all enabled modules along with the explanation what module/option requires it. For example Enabled ITKGDCM, requested by ITK_BUILD_DEFAULT_MODULES. Look for what is requesting GDCM for you.


Oh, the IO module name is the other way around, sorry! Try:
