Building Slicer v4.11.20210226 on Win10

Development
1

I tried to build Slicer at tag v4.11.20210226 on Win10. Git version is 2.31.1. CMake version is 3.19.2. Here is what I did:

cd C:/
mkdir Git
cd Git
git clone https://github.com/Slicer/Slicer.git S4
cd S4
git reset --hard v4.11.20210226
cd ..
mkdir S4R
cd S4R
cmake -G "Visual Studio 16 2019" -A x64 -DQt5_DIR:PATH=C:/Qt/5.15.2/msvc2019_64/lib/cmake/Qt5 C:/Git/S4
cmake --build . --config Release

It seems VTK does not build due to not being able to clone on of its remote Git repositories. This is the error I get:

Creating directories for 'VTK'

  Cloning into 'VTK'...

  Note: checking out '97904fdcc7e73446b3131f32eac9fc9781b23c2d'.

  You are in 'detached HEAD' state. You can look around, make experimental
  changes and commit them, and you can discard any commits you make in this
  state without impacting any branches by performing another checkout.

  If you want to create a new branch to retain commits you create, you may
  do so (now or later) by using -b with the checkout command again. Example:

    git checkout -b <new-branch-name>

I made some progress. Initially I used cygwin and that seemed to have led to problems. I just now saw that there is a note about using cygwin in the build guide. I then switched to cmd.exe and used a git.exe different from the git version installed within cygwin. Now the problematic part (VTK) is compiling.

I got another error, this time with an ITK related function. The fix for that is described here and here.
