Hi, guys.

I’m trying to install **Slicer release 4.10.2** in my Linux Mint 18.3 Sylvia Desktop.  
I correctly installed **CMake 3.13.4 and Qt 5.11.0**.  
I go with CMake, configure and generate, everything goes ok!

But when I do **sudo make** in the slicer build folder… it runs and **crashes** with the following error:

```
CMake Error at PCRE-prefix/src/PCRE-stamp/download-PCRE.cmake:159 (message):
Each download failed!
error: downloading 
'https://github.com/Slicer/SlicerBinaryDependencies/releases/download/PCRE/pcre-8.38.tar.gz' failed
     status_code: 1
     status_string: "Unsupported protocol"
     log:
     --- LOG BEGIN ---
     Protocol "https" not supported or disabled in libcurl

Closing connection -1

```

As trials to fix it, I did reinstall to the latest version **OpenSSL** and **Clurl --with-ssl** , with the last one not working well (I then installed that through synaptic). But no success at all.

Any help is very welcome.  
Thanks!

P.S. I just installed pure ITK 5.0, everything worked very well!

This error seems to be a CMake SSL configuration error, which is not related to Slicer. There are several similar error reports on the web (such as [this](https://stackoverflow.com/questions/29816529/unsupported-protocol-while-download-tar-gz-package)) - one of the suggested solutions should work for you, too.

Thanks, Andrass.

Checking that right now!

Just curious, why do you use sudo for building Slicer?

I guess I do this just to be sure it will not stop with some “permission denied” error… haha

**[SOLVED]**

In fact, as Andrass pointed out, it was a **CMAKE PROBLEM**. I did as it follows:

install the **lib libcurl4-openssl-dev:** :

```
sudo apt-get install libcurl4-openssl-dev

```

**Rebuild CMake from source** with the following comands:

```
sudo ./bootstrap --system-curl
Make
Make install

```

Finally, I ran the standard recommendations for building 3D SLICER!

Thanks for the update.

To simplify your workflow. Instead of building CMake from source, I suggest you download the CMake binaries available at [https://cmake.org/download/](https://cmake.org/download/)
