I have the following error while doing this command on Linux : `pip3 install cmake --upgrade`.

```
Collecting cmake

```

How can I solve this ?

It appears as though a build dependency is missing? @jcfr

I tried to force it to different versions with  
`pip3 install 'cmake==3.1x.x' --upgrade`

And I have this error only with the version 3.16.3, the one taken by default with --upgrade parameter.  
Also, I don’t have this error on Mac, only on Debian.

Which python version are you using ?

Here is what is happening:

- we are currently building CMake wheels for manylinux2010. See [scikit-build/cmake-python-distributions#78](https://github.com/scikit-build/cmake-python-distributions/issues/78) for the rational
- and python 3.7.3 on debian expects manylinux1 wheels:

```auto
docker run -ti --rm debian:buster

# then from within container
apt update
apt install python3-pip
python3 -c "from pip._internal.pep425tags import get_supported; print('\n'.join('-'.join(x) for x in get_supported()))"

Until [scikit-build/cmake-python-distributions#78](https://github.com/scikit-build/cmake-python-distributions/issues/78) is addressed, you will **not** be able to install recent CMake wheels.

Note that building cmake using the source distributions is not something we support. I will probably look into removing the sdist (source distribution) from pypi completely.
