I'm not sure I follow: the above sed command seems to affect the kolab-utils 
package, but it's the libkolabxml package that won't build. And neither the 
old nor the new version of the LibkolabxmlConfigVersion.cmake.in file seem to 
correct the problem.

However, I did think that maybe something related to the cmake configuration 
might be the problem; there are the following files listed in the libkolabxml-
dev.install file (along with other development libraries and headers):

usr/lib/cmake/Libkolabxml/LibkolabxmlTargets.cmake
usr/lib/cmake/Libkolabxml/LibkolabxmlTargets-noconfig.cmake
usr/lib/cmake/Libkolabxml/LibkolabxmlConfig.cmake
usr/lib/cmake/Libkolabxml/LibkolabxmlConfigVersion.cmake

Meanwhile, I only find the following cmake-related files in the sources:

cmake/modules/FindLibkolabxmlDependencies.cmake
cmake/modules/LibkolabxmlConfig.cmake.in
cmake/modules/LibkolabxmlConfigVersion.cmake.in
libkolabxml-version.h.cmake

Sadly, I'm not familiar with the underlying build system, nor with cmake, but 
it looks like CMakeLists.txt produces the otherwise absent 
LibkolabxmlTargets.cmake file as follows:

install(EXPORT LibkolabxmlExport DESTINATION ${CMAKECONFIG_INSTALL_DIR} FILE 
LibkolabxmlTargets.cmake )

How it might produce a -noconfig variant is unknown to me at the moment.
