Hi,

I'm involved in the Rosegarden project (www.rosegardenmusic.com), a KDE3 
application. We aren't yet ready for a KDE4 migration, but we have moved 
recently to CMake. 

I didn't find anything for KDE3 translations and documentation management, so 
I  wrote some macros. Perhaps somebody can review and tweak them for KDE4.

FindMSGFMT.cmake
http://rosegarden.svn.sourceforge.net/viewvc/*checkout*/rosegarden/trunk/rosegarden/cmake_admin/FindMSGFMT.cmake

It tries to find the msgfmt program, defines the following variables: 
MSGFMT_FOUND and MSGFMT_EXECUTABLE, and provides a macro: ADD_TRANSLATIONS() 
that can be used to process a po/ directory. The macro takes as the first 
argument the project base name, and then a list of ".po" files. It adds a 
"translations" custom target, and takes care of installing the resulting  
"basename.mo" files at the proper locations.

FindMEINPROC.cmake 
http://rosegarden.svn.sourceforge.net/viewvc/*checkout*/rosegarden/trunk/rosegarden/cmake_admin/FindMEINPROC.cmake

It finds the meinproc program, defines the variables MEINPROC_FOUND and  
MEINPROC_EXECUTABLE, and provides the macro: ADD_DOCS(). The macro takes as 
the first argument the project base name, and then a list of directories 
where the documents (index.docbook) and other resources reside.

Here are some samples from the Rosegarden build system. First, you  should 
include in the main CMakeLists.txt the checks for the utility programs:

	FIND_PACKAGE(MSGFMT REQUIRED)
	IF(MSGFMT_FOUND)
	    MESSAGE(STATUS "Program msgfmt found (${MSGFMT_EXECUTABLE})")
	ENDIF(MSGFMT_FOUND)

	FIND_PACKAGE(MEINPROC REQUIRED)
	IF(MEINPROC_FOUND)
	    MESSAGE(STATUS "Program meinproc found (${MEINPROC_EXECUTABLE})")
	ENDIF(MEINPROC_FOUND)

In the po/ directory you can add a CMakeLists.txt with:

	FILE(GLOB PO_FILES *.po)
	ADD_TRANSLATIONS(rosegarden ${PO_FILES})

And in your documentation directory:

	ADD_DOCS(rosegarden en es ja sv)

Where en/ es/ etc. are directories containing KDE style documentation. 
The latest Rosegarden releases (1.5.x) available at SourceForge are using  
these macros. http://sourceforge.net/projects/rosegarden/
