If you do not need to coinstall Qt4 variant along with Qt5 this need to be done:
1. add a cmake configure option e.g. BUILD_QT4 or similar to enable building for Qt4. 2. find Qt4 instead of Qt5 3. replace references to Qt5 by related Qt4 ones 3.1. all CMakeLists.txt e.g. Qt5::Core by Qt4::QtCore and similar 3.2. in src/LibAlkimiaConfig.cmake.in (see find_dependency) 3.3. in src/libalkimia.pc.in (replace reference to Qt5Core, Qt5DBus by QtCore, QtDBus) To have a Qt4 based binary package coinstalled with Qt5 the following stuff need to be changed too: 4. Install cmake configuration files into different sub dir (Qt5: LibAlkimia-<version>) e.g. LibAlkimiaQt4-<version> 5. Create different pkgconfig file e.g. libalkimiaQt4.pc or similar 6. Create different libalkimia shared object file e.g. libalkimia-qt4.so.xxx using set_target_properties (... OUTPUT_NAME) 7. Install header files into a separate sub dir to not be overwritten by Qt5 installation e.g. /usr/include/alkimia-qt4 or similar (there may be a distribution standard for that, I don't know) 8. Patch kmymoney in branch 4.8 to use the Qt4 alkimia version. Ralf
