My environment is:
window 10 64 bit
vs 2015 64 bit
Python 3.7.6 (default, Jan 8 2020, 20:23:39) [MSC v.1916 64 bit (AMD64)] :: Anaconda, Inc. on win32
cmake 3.16.0-rc4
Python 3.7.6 (default, Jan 8 2020, 20:23:39) [MSC v.1916 64 bit (AMD64)] ::
This means it is a 64 bit Python.
LNK111: module machine ‘x64’ conflicts with target machine type ‘X86’
This means that the ITK Visual Studio is building for 32-bit system: since we are building against 64 bit Python, we want to build for a 64-bit system.
Delete the ITK build tree, then run the initial CMake configuration again. On the first CMake configuration, the target build generator is selected; change to a 64-bit Visual Studio generator.
LNK110: cannot open file ‘python37_d.lib’
This indicates a debug build and linking against the _d debug library; you probably do not want that. Select the Release versus the Debug build configuration in Visual Studio. Also, check the PYTHON_LIBRARY setting in the CMake configuration and make sure it is not pointing to the _d library.
