I’m trying to build ParaView in MacOS. I went to the repository `https://gitlab.kitware.com/paraview/paraview/tree/master` which lead me to build paraview-superbuild
`https://gitlab.kitware.com/paraview/paraview-superbuild/tree/v5.7.0``
Following instructions I executed
```auto
$ cd paraview-superbuild
$ git fetch origin # ensure you have the latest state from the main repo
$ git checkout v5.7.0 # replace `v5.7.0` with tag name of your choice
$ git submodule update
```
Then
```auto
$ mkdir build
$ cd build
$ cmake ..
```
And I’m getting the error
```auto
-- Found Git: /usr/local/bin/git (found version "2.21.0")
-- Determined source version for paraview: 5.7.0
CMake Error at superbuild/cmake/SuperbuildMacros.cmake:481 (message):
The build tree appears to be inside of the git repository located at
/Users/username/Desktop/dev/paraview/paraview-superbuild. This interferes
with the way the superbuild applies patches to projects and is not
supported. Please relocate the build tree to a directory which is not
under a git repository.
```
What is happening here? Was cmake execute in the right folder? because there are more CMakeList.txt inside paraview-superbuild.
Thanks!

The error says what it means to me at least 🙂 (wording improvements would be greatly appreciated). Your build tree is under a Git repository checkout (at the path given). We use `git apply` to apply patches to the sources that the superbuild builds and this changes behavior when the build tree is under a git repository in a way that can’t be worked around (AFAIK), so we error out on it. Basically, instead of `mkdir build`, use `mkdir ../build`.

Okay, thanks for the reply.
I did
`mkdir ../build`
I`cmake ../paraview-superbuild`
But still got the same error 🤔

Hmm. What path does it say the git repository is located at? Your build tree needs to be outside (I prefer a sibling directory, but it’s up to you) of that directory.
