FindMEMKIND.cmake support

Development
#1

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, 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

#2

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 ERRORs 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:

CMake Warning at /usr/local/lib/cmake/vtk-9.1/VTK-vtk-module-find-packages.cmake:574 (find_package):

   "MEMKIND_DIR" to a directory containing one of the above files.  If

 Could not find the VTK package due to a missing dependency: MEMKIND
  1. For FreeCAD

Almost the same, but configure gave me an ERROR:

 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 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.
