Php5-devel on sles12.5

All sorts of php5 packages are available, but not php5-devel.
I have these repositories enabled:
SLES12-SP5-Pool
SLES12-SP5-Updates
SLE-SDK12-SP5-Pool
SLE-SDK12-SP5-Updates
SUSE-PackageHub-12-SP5-Standard-Pool
SLE-Module-Toolchain12-Pool
SLE-Module-Toolchain12-Updates
SLE-Module-Web-Scripting12-Pool
SLE-Module-Web-Scripting12-Source-Pool
SLE-Module-Web-Scripting12-Updates

When I installed php5 and other related packages, I got php5-5.5.14-109.82.1.
If I look on scc.suse.com and do a package search, the best I can find is php5-devel-5.5.14-109.76.1, but that’s for SLES12 SP4.
Is there any alternative short of building from the php5 source rpm?

Is there any alternative short of building from the php5 source rpm?

The srcpackage, php5-5.5.14-109.82.1, from SLE-Module-Web-Scripting12-Updates
does not claim to be able to build php5-devel.
It might contain all the source files, so there might be a way to do it, but probably not as simple as running rpmbuild.

Perhaps using php5-devel from SP4 would work for building an extension to use in later versions php5.
