@moselhy You can find it in the build tree. For example:

```auto
$ git clone https://github.com/moselhy/SequenceRegistration
$ mkdir SequenceRegistration-build
$ cd SequenceRegistration-build/
$ cmake -DCMAKE_BUILD_TYPE:STRING=Release -DSlicer_DIR:PATH=/home/jcfr/Projects/Slicer-2-build/Slicer-build/ ../SequenceRegistration

$ make -j6
[...]
-- Configuring Scripted module: Elastix4D
-- Extension description has been written to: /tmp/SequenceRegistration-build/SequenceRegistration.s4ext <------------
[...]
-- Build files have been written to: /tmp/SequenceRegistration-build

$ pwd
/tmp/SequenceRegistration-build

$ ls *.s4ext
SequenceRegistration.s4ext

```

You should also see the following message reported when configuring:

```auto
Extension description has been written to: /tmp/SequenceRegistration-build/SequenceRegistration.s4ext

```

Content of the generated file:

```auto
$ cat SequenceRegistration.s4ext
[...]
# This is source code manager (i.e. svn)
scm git
scmurl https://github.com/moselhy/SequenceRegistration
scmrevision 39fe467

# list dependencies

# - The dependencies will be built first
