When I build the InsightToolkit 4.13.2 release, the libraries that are created are labelled version 4.13.1.  
Any idea what is going wrong ?

You might need to do a clean build. The [version](https://github.com/InsightSoftwareConsortium/ITK/blob/release-4.13/CMakeLists.txt#L27) seems to be properly set.

It seems at the cmake configuration stage the patch version number is not always being used to construct the expected file names.

Here is a small script to reproduce the issue.

```auto
#!/bin/sh

git clone -b release-4.13 https://github.com/InsightSoftwareConsortium/ITK

dest=`pwd`/dest
mkdir ${dest}

mkdir build
cd build

cmake \
    -DCMAKE_INSTALL_PREFIX=${dest} \
    -DBUILD_EXAMPLES:BOOL=OFF \
    -DBUILD_TESTING:BOOL=OFF \
    -DBUILD_SHARED_LIBS:BOOL=ON \
    -DCMAKE_BUILD_TYPE:STRING=Release \
    -DCMAKE_CXX_FLAGS_RELEASE:STRING="-O3 -DNDEBUG" \
    ../ITK

make

exit 0

```

@warfield thanks for the nice reproducible script.

The file names are currently created as intended:

```auto
[...]
libITKSpatialObjects-4.13.so
libITKSpatialObjects-4.13.so.1
[...]

```

To explain, the trailing `.1` is always `.1` and does not change with the patch version.
