I do not believe the issue is within GDCM codebase:

Steps:

$ mkdir /tmp/p && cd /tmp/p
$ sudo apt-get install libgdcm2-dev
$ cat CMakeLists.txt
cmake_minimum_required(VERSION 3.0)
find_package(GDCM REQUIRED)
message("found: ${GDCM_FOUND}")
$ cmake . | grep found
found: 1

My guess is that something recently broke in cmake. For reference:

$ cmake --debug-output --trace --find-package -DNAME=GDCM
-DLANGUAGE=CXX -DCOMPILER_ID=GNU -DMODE=COMPILE
