Description

I am configuring the GitHub Actions for the module ITKIOTransformDCMTK and this module uses DCMTK as a dependency in ITK.

Steps to Reproduce

The GitHub Actions configuration can be found here, or you can follow the steps below.

git clone https://github.com/InsightSoftwareConsortium/ITK.git
cd ITK
git checkout v5.1.1

cd ..
mkdir ITK-build
cd ITK-build
call "C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Auxiliary\Build\vcvars64.bat"
cmake -DCMAKE_C_COMPILER:FILEPATH="cl.exe" -DModule_ITKDCMTK:BOOL=ON -   DModule_ITKIODCMTK:BOOL=ON -DBUILD_SHARED_LIBS:BOOL=ON -DCMAKE_CXX_COMPILER="cl.exe" -DCMAKE_BUILD_TYPE:STRING="Release" -DBUILD_TESTING:BOOL=OFF -GNinja ../ITK
ninja

#ITKIOTranformDCMTK configuration
ctest --output-on-failure -j 2 -V -S dashboard.cmake

Expected behavior

No warnings generated when compiled with DCMTK.

Actual behavior

In cdash, I get the following compiler warnings when building ITK and ITKIOTransformDCMTK output.
