Just did and update and tried to rebuild Slicer. I get the error:

loading initial cache file /home/lorensen/ProjectsGIT/Slicer-Superbuild/zlib-prefix/tmp/zlib-cache-Release.cmake  
CMake Error at CMakeLists.txt:3 (PROJECT):  
Generator

```
Unix Makefiles

```

does not support toolset specification, but toolset

```
USES_TERMINAL_DOWNLOAD

```

was specified.

– Configuring incomplete, errors occurred!

I did a fresh build on ubuntu with make -j20 and got an error that had scrolled off. When I did a second build it completed with no error. I’ll try another fresh build into a log file and see if it’s the same issue you reported.

@jcfr looks like your commit:

ENH: Update ExternalProjectDependency based on commontk/Artichoke@5ee3d50

This commit improves the support for Ninja generator by ensuring the
option USES_TERMINAL_* options are set to give Ninja access to the
terminal when the CMake version supports it.

See https://cmake.org/cmake/help/v3.4/module/ExternalProject.html

Also Update CTK to integrate a similar update:

$ git shortlog 19fc678..b8587e5 --no-merges

      Update ExternalProjectDependency based on commontk/Artichoke@5ee3d50
      ENH: ExternalProjecDependency: Re-apply commontk/CTK@6cc426b

@jcfr  
Interesting, I’m using cmake version 3.3.2 and the test to use the new USES\_TERMINAL\_\* says:  
if(CMAKE\_VERSION VERSION\_GREATER “3.3”)  
# USES\_TERMINAL\_\* options were introduced in CMake 3.4

Looks like the test is wrong.

Another clean build completed without error. Probably a race condition.

IMy cmake is 3.5.1 so I didn’t see the TERMINAL issue.

In Slicer/CMake/ExternalProjectDependency.cmake

Test should be:  
if(CMAKE\_VERSION VERSION\_GREATER “3.3.2”)  
NOT  
if(CMAKE\_VERSION VERSION\_GREATER “3.3”)

The same error exists in CTK. I will update my cmake, but I think this error should be fixed.

As soon CI returns green, I will update CTK and Slicer.
