Introduction
CMake configuration files were rewritten by Veaceslav Munteanu <veaceslav dot munteanu90 at gmail dot com> at 10 June 2014. The aim of new configuration was to reduce the linking overhead and improve CPU utilization while still keeping the modular design implemented by Teemu Rytilahti
CMake Structure
Independent Cmake configuration is presents in following folders:
- digikam-software-compilation
- core
- extra
- docs
The rewrite touched mostly the core folder.
CMake executables for core
Core cmake will link the following executable:
- digikam
- showfoto
- digikam database server - if compilation is enabled in cmake files
- various test executables - if testing is enabled
each of them depend on various sources which must be compiled before.
To avoid linking overhead and make a better use of sources there are some dynamic libs.
- digikamcore - core components used by almost all executables
- digikamdatabase - database components, also used together with digikamcore
- imageplugins - image plugin implementation
- kio modules - soon to be deprecated
Warning
Please add sources to digikam core or digikam database only if they don't depend on any big component from digikam main executable. These two shared libs must be kept small because they link in a lot of places
Static Libraries
Currently cmake configuration features 4 shared libs:
- queuemanager
- advancedrename
- importui
- baloowrap
Warning
Avoid making static libs, use OBJECT libraries instead. Only make STATIC libraries which does not depend on other digikam code. Also make sure you put the PRIVATE parameter when setting the target_link_libraries.
