>Description:
x11/kdelibs4 has a cmake file(cmake/modules/FindDocBookXML.cmake),
which tries to detect if docbook-xml is installed or not.

However, under pkgsrc's build environment, cmake cannot find docbook-xml
because CMAKE_SYSTEM_PREFIX_PATH doesn't contain LOCALBASE.

>How-To-Repeat:
% cd x11/kdelibs4
% make

compile failed with this message.

*** Error code 1

Stop.
make: stopped in /home/pkgsrc/x11/kdelibs4

>Fix:
There are several possible solutions.

1. Create buildlink3.mk to textproc/docbook-xml.
   pkgsrc's CMAKE_SYSTEM_PREFIX_PATH has $ENV{BUILDLINK_DIR}, this makes
   cmake succeed.

2. Add LOCALBASE to CMAKE_SYSTEM_PREFIX_PATH in 
mk/cmake-Modules/Platform/UnixPaths.cmake.

3. Add a patch for x11/kdelibs4 to force cmake to find docbook-xml from 
LOCALBASE.
