Hi, all:

1. I happened to realize it’s **NOT** quite convenient to build VTK from source **WITHOUT**  **memkind**. So, I enabled memkind `VTK_USE_MEMKIND ON`.

However, default repository of Ubuntu 22.04, or from source of [memkind](https://github.com/memkind/memkind), there is **NO** support for **CMake** build. I mean, it seems there would be **NO MEMKIND\_DIR**.

1. Furthermore, when I tried to build **PCL** based on **VTK** , it’s **NOT** able to find **MEMKIND::MEMKIND** …

So… any suggestions?

Cheers

Right, instead `FindMEMKIND` is used. Is there some reason why it doesn’t work for you? Do you have any error messages?

Hi, @ben.boeckel

Yes, I did meet some **ERROR** s when I tried to build **PCL** :

1. For **PCL**  
During Configuration, I set  
`MEMKIND_DIR MEMKIND_DIR-NOTFOUND`

But, when I tried to **configure** , I got **warning** :

```nohighlight
CMake Warning at /usr/local/lib/cmake/vtk-9.1/VTK-vtk-module-find-packages.cmake:574 (find_package):
   By not providing "FindMEMKIND.cmake" in CMAKE_MODULE_PATH this project has

   CMake did not find one.

   of the following names:

     memkind-config.cmake

   Add the installation prefix of "MEMKIND" to CMAKE_PREFIX_PATH or set
   "MEMKIND_DIR" to a directory containing one of the above files. If
   "MEMKIND" provides a separate development package or SDK, be sure it has

 Could not find the VTK package due to a missing dependency: MEMKIND

```

1. For **FreeCAD**

Almost the same, but **configure** gave me an **ERROR** :

```nohighlight

 Configuring incomplete, errors occurred!

```

So, any further suggestions?

Ah ha! The `FindMEMKIND` module needs installed. I’ll fix that. Thanks for the report.

Added to [https://gitlab.kitware.com/vtk/vtk/-/merge\_requests/9203](https://gitlab.kitware.com/vtk/vtk/-/merge_requests/9203) which fixed some other things I noticed when first looking at this.

I am curious why it is hard to build VTK without memkind? It should be optional.

_If_ there are users of that feature in VTK it would be great to hear about it!

I build it without memkind all the time. It seems you did build it with memkind. If that’s the case, just about everything will also need to know because `CommonCore` requires it.
