Could not find a package configuration file provided by "DICOM" with any of the following names

[MikeKen-Ken]

In CMakeLists.txt, I use the code
find_package(DICOM CONFIG REQUIRED) if(DICOM_FOUND) include(${DICOM_USE_FILE}) endif() set(VTK_DICOM_LIBRARIES vtkDICOM)

But I get an error 'Could not find a package configuration file provided by "DICOM" with any of the following names'

Can you help me to tell me why? I am using vcpkg installation vtk-dicom, version 0.8.14

Thank you.

The documentation at https://dgobbi.github.io/vtk-dicom/doc/api/installation.html is old, I will fix it this weekend. The way that I use find_package is like this, with nothing else:

find_package(DICOM)

Nothing else should be needed, because this should set VTK_DICOM_LIBRARIES automatically.
There is no USE_FILE anymore, since VTK deprecated its own USE_FILE.
The value of VTK_DICOM_LIBRARIES is always VTK::DICOM, so it is safe to do this:

target_link_libraries(MyProgram VTK::DICOM)

I've never used vcpkg, but I think that everything that I say here is also true for vcpkg. Please let me know if you discover more problems.

The error I get is this

I found someone who had a similar problem.

But I installed the latest version 0.8.14, and I found the corresponding file in the installation directory. I'm not sure if it's relevant to the above question.

Thank you very much indeed for your help.

Have you tried setting variables to tell cmake where to look for the config file?

You can set the DICOM_DIR cmake variable to the absolute path of the dicom-0.8 directory,
or you can set the CMAKE_PREFIX_PATH environment variable to one directory above this. E.g:

DICOM_DIR=/full/path/to/vtk-dicom/dicom-0.8

CMAKE_PREFIX_PATH=/full/path/to/vtk-dicom

I don't know why vcpkg doesn't put the configure file where it will be found automatically. If you can see any obvious differences between vtk-dicom and other vcpkg packages, then let me know, just in case there's something that I can fix in the vtk-dicom repository.
