Why not using system gdcm?

[alcir]

Hello.

For instance on Fedora.
sudo dnf install gdcm-devel

Then in CMakeLists.txt

FIND_LIBRARY(COMMON_LIBRARY       NAMES gdcmCommon)
FIND_LIBRARY(IOD_LIBRARY       NAMES gdcmIOD)
FIND_LIBRARY(MSFF_LIBRARY       NAMES gdcmMSFF)
FIND_LIBRARY(DSED_LIBRARY       NAMES gdcmDSED)
FIND_LIBRARY(DICT_LIBRARY       NAMES gdcmDICT)

should work, isn't it?

You are talking about the Dockerfile? Changing the base image? I am sometimes running into problems with cmake`s finding of installed packages - because I don't understand the mechanism...

You are talking about the Dockerfile?

No no. I'm compiling it on a Fedora host, Docker is not involved.

And instead of downloading GDCM sources, I install the gdcm-devel package from the distribution repository.
So, if I modify the file CMakeLists.txt getting rid of the references to the GDCM source directory, cmake seems to work with the development package shipped by the Linux Distribution.

Thanks.

So.
Adding this

FIND_PACKAGE(GDCM REQUIRED)
if(GDCM_FOUND)
  message(STATUS Found GDCM)
  include(${GDCM_USE_FILE})
endif(GDCM_FOUND)

and removing all the references to GDCM directories, it builds successfully using the gdcm devel packages shipped by the distribution (at least on Fedora).
