When I envoke cmake I get this error:
```
CMake Error: Could not find CMAKE_ROOT !!!
CMake has most likely not been installed correctly.
```
I use cmake version 3.10.2 on Xubuntu 18.04 64bit.
What can I do?
Greetings
Peter

It sounds like you’ve moved the `cmake` executable out of its installation tree. It needs to be kept in the same directory structure as `ctest`, `cpack`, `ccmake`, `cmake-gui`, and its `Modules` and `Templates` directory.
Is this the case?

No. But I have cmake both in /bin and in /usr/bin. This is probably a wrong thing.
I had just installed cmake 3.16.something and **cmake --version** tells me it is still cmake 3.10.something. I think I messed up the installation somehow.
Any chance to correct this?

What installation method did you use to install 3.10 and 3.16?

3.10 was already installed on OS installation or unnotieced as a dependency (via APT).
3.16 was downloaded form [https://cmake.org/download/](https://cmake.org/download/) and I followed the instructons there (If I remember correctly: ./bootstrap && make && sudo make install)

Hmmm. So both installations appear to be valid.
How did you get CMake into `/bin`? Did you manually copy it in there? `/bin/cmake` may be the one that’s causing issues.

Yes I copied it there by hand. ☹

Please delete `/bin/cmake`. There’s no reason for it to live in `/bin`, and it’s failing because it can’t find its module files (it’s looking in `/share/cmake-3.10/Modules`, which obviously doesn’t exist.)

Also, we have our own [APT repository](https://apt.kitware.com/) which always hosts the latest CMake builds for Ubuntu. We even publish the release candidates as an optional add-on. This would probably be easier than managing the installation yourself 🙂

Yes that would certainly be easier. I will go there.
I deleted /bin/cmake. Any other program to delete? maybe /bin/ctest and whatelse?

- `/bin/cpack`
- `/bin/ccmake`

Ander deleting those files I took the APT package and now it works fine with 3.16 without error.
Is it possible to mark this thread as “Solved”?

Yes, I will do so.

Also, you may want to remove the CMake installation from `/usr/local` - it may be shadowing the “correct” one in `/usr`.
