Hello!
I’m trying to build ParaView on Ubuntu 20.04 LTS. I’ve followed the instructions on [ParaView/build.md at master · Kitware/ParaView · GitHub](https://github.com/Kitware/ParaView/blob/master/Documentation/dev/build.md)
After sucessfully (?) setting things up with cmake, I get an error when i try to ninja-build. The error is:
ninja: error: ‘vtkm::tbb-NOTFOUND’, needed by ‘lib/libvtkm\_cont-pv5.9.so.1’, missing and no known rule to make it
More details below. I would really appreciate some help. I have been looking around for a solution for quite some time now, but I am at a loss for how to solve this.
```

It would appear as though VTK-m did not find TBB. It should error in that case instead of making this occur. I have [an issue](https://gitlab.kitware.com/vtk/vtk-m/-/issues/609) to improve VTK-m’s third party handling.

Do you have any idea of how to fix this issue?
Before building, I installed all of the prerequisite packages listed in [ParaView/build.md](https://github.com/Kitware/ParaView/blob/master/Documentation/dev/build.md)
```
sudo apt-get install git cmake build-essential libgl1-mesa-dev libxt-dev qt5-default libqt5x11extras5-dev libqt5help5 qttools5-dev qtxmlpatterns5-dev-tools libqt5svg5-dev python3-dev python3-numpy libopenmpi-dev libtbb-dev ninja-build
```
When I list installed packages related to vtk and tbb I find
```
gfield@gfield-desktop:/usr/local/src/OpenFOAM-v2012$ apt list --installed *vtk*
Listing... Done
libvtk6.3/focal,now 6.3.0+dfsg2-5build2 amd64 [installed,automatic]

Do I need to install/build VTK-m before building ParaView? How come that is not listed as a dependency?

VTK-m is in ParaView because it is in VTK itself (vendored and such). I don’t know why VTK-m isn’t finding TBB out of the box. Some `--debug-find` output around VTK-m’s `FindTBB` searchings could help.

Hmm. I ran
```
sudo ninja -d explain
```
A snapshot of the output is
```

```
The corresponding directories can be found in my build-directory, but they seem to be empty. I have tried building in my source-directory as well, but that does not work. I get the following error message:
```
CMake Error at CMakeLists.txt:36 (message):
ParaView requires an out-of-source build. Please create a separate binary
directory and run CMake there.
```
(I have one directory called paraview-source/, and one called paraview-build/, both located at /usr/local/src/.)
Could something have gone awry in the first step (i.e. setting up makefiles with cmake)? I’m still at a loss of what to do.

1. Why are you running as `sudo`? You really shouldn’t build as `sudo` (install can make sense). (Later info shows you’re building in `/usr/local`…why not build in your `$HOME`?)
2. It seems that you once configured ParaView from its source directory. Remove `CMakeCache.txt` and `CMakeFiles` from the source tree and try again.
3. Finding TBB has nothing to do with `ninja -d explain`. You can run `cmake --debug-find $other_configure_args` to get that information.

FYI, I’m seeing the same problem with Ubuntu 20.04. It happens with 655528fc9b64cd3a59eb00212c8b18afebda8264 (3/11), but not with 1e857afe005c24c79fb2146180005ae7e992e929 (3/5).

The difference is that in VTK, we now try to use `TBBConfig.cmake` if possible. Could someone please get a backtrace as to how TBB is being found within VTK-m with this change? Using `--debug-find` and snipping to around VTK-m’s `find_package(TBB)` would be ideal.

Hello! I haven’t had time to work on this for a couple of days, but here comes a few answers.
**1. Why are you running as `sudo`? You really shouldn’t build as `sudo` (install can make sense). (Later info shows you’re building in `/usr/local`…why not build in your `$HOME`?)**
I have gotten the impression that it is a good habit to keep local software (intended for any user) in /usr/local. I’m no expert Linux user though, so I could be wrong. 🙂
**2. It seems that you once configured ParaView from its source directory. Remove `CMakeCache.txt` and `CMakeFiles` from the source tree and try again.**
I tried building in the source directory (didn’t work), when the out-of-source build didn’t work. I have now removed the mentioned files and directories from the source directory.
**3. Finding TBB has nothing to do with `ninja -d explain`. You can run `cmake --debug-find $other_configure_args` to get that information.**
I have ran cmake --debug-output (couldn’t find --debug-find). There’s over 10,000 output lines, but only 30 of them contain “tbb”. Below I printed a snapshot. (The others are more or less identical, but with other sub-directories of /usr/local/src/paraview-build/VTK/ThirdParty/vtkm/vtkvtkm/vtk-m/vtkm/). I can’t find any relevant errors/warnings.

`sudo` is usually left for the _install_ step. Building can happen anywhere and should not be done with root permissions.

Ah, that’s a newer CMake feature then. It was added in CMake 3.17. You can download a newer version from CMake’s [release page](https://github.com/Kitware/CMake/releases); there’s no need to install it globally because you can just extract the Linux tarball and use it from wherever that is.

I’m looking for `--debug-find` output around VTK-m’s TBB searching to know why it fails.
