When I compile ITK 5.0.1 on Windows (VS 2015 x64, BUILD\_SHARED\_LIBS=ON, Module\_ITKIODCMTK=ON, otherwise default configuration) I get linker errors (see attached log file). I searched for those symbols, but found stuff related to Android/NVIDIA ([here](https://gitlab.incom.co/CM-Shield/android_device_nvidia_shield-common/blob/b992bd5fc1b87992e7e77ad2324b575890632f46/shims/icu_shim.c)).

I just did the described build, and it succeeded for me. My build log is here:

I started from a clean build directory (that is, not an incremental build), and used CMake 3.15.2.

strange. I repeated the build (always starting from clean build directory), this time with CMake 3.15.2, but still get the missing symbols.

I did run into an unrelated [issue](https://github.com/InsightSoftwareConsortium/ITKIOMeshSTL/issues/29) while trying to reproduce your problem.
