If you run:
```auto
$ cmake --version
```
I think you will find that it will report version 3.10.2.
Where did you install the new CMake? I’m guessing you don’t have it in your `$PATH`.

This is starting to look like an only partly-installed CMake. When you install the `cmake` binary, you need to install all of the module files too.
What do you get for:
```auto
$ which cmake
```
? And did you install 3.15.6 into `/usr/local/bin`?

$which cmake
/usr/local/bin/cmake
i am not sure the new version was there (usr/local/bin)
since i have 2 version here.

What OS are you using? I would suggest uninstalling the OS version of CMake to ensure you only have one version. For example, if you’re using Ubuntu, run:
```auto
$ sudo apt-get remove cmake
```
