Where to find this code

Jesus,
the whole process of generation of the KMyMoney artifacts is divided into these parts:
a) configuration
b) compilation / linkage
c) installation
Step a) is where cmake comes into play. Its job is to convert the meta information provided in CMakeLists.txt files into lower level Makefiles (depending on the build tool/generator used). This step caches some information which will not be re-evaluated if you re-run cmake. To get a full scan remove build/CMakeCache.txt and re-run cmake. Removing CMakeCache.txt also wipes all the settings you have made using ccmake.
Step b) is invoked by calling 'make' and compiles and links the artifacts comprising the application, that is the executables (yes, the testcases as well), shared libs and plugins. At the end they are all located in build/bin.
Step c) moves all the necessary files (executable, shared libs, plugins, icons, templates, etc.) into the location of your KDE install. This is performed by running 'sudo make install/fast'.
To remove an installed version, I simply use this the following sequence in the build sub-directory:
sudo -s
xargs rm < install_manifest.txt
exit
Having two sandboxes (one with master and one with 5.0) and can easily switch between the two of them. E.g. from stable to master:
cd stable/build
sudo -s
xargs rm < install_manifest.txt
exit
cd ../../master/build
sudo make install/fast
This will make sure that all the files are recent. Especially for plugins, step c) is very important. If you omit it, the debugger will use the newly compiled executable and shared objects from the build/bin directory, but not the plugins. It will use the old ones found installed. As Jack pointed out, not having the most recent plugin installed may be the cause to the problem you encounter.
BTW: KMyMoney tells you on the command line where it picks up the plugins during startup, e.g.
Located plugin "/usr/lib64/qt5/plugins/kmymoney/konlinetasks_sepa.so" Validity true
Located plugin "/usr/lib64/qt5/plugins/kmymoney/csvimporter.so" Validity true
.
.
Loading "/usr/lib64/qt5/plugins/kmymoney/budgetview.so"
Plugins: budgetview loaded
Loading "/usr/lib64/qt5/plugins/kmymoney/checkprinting.so"
Plugins: checkprinting loaded
.
.
Hope that helps.
Thomas
