As this comes up quite often I retried my approach from scratch. You "just"
need all build dependencies installed. I did it with Linux, but it should be
the same on windows except one command (and you have to replace cd). If you
test it and it works as well, I can publish it on techbase. With windows
specific stuff it would even be better.
# Get sources
git clone git://anongit.kde.org/kmymoney
# Create directory for out of source build
# Run cmake and set an install prefix
# "make install" will copy all files there
cmake -DCMAKE_INSTALL_PREFIX=../install/ ../
# Build and install
# Give KDE's trader the chance to find the new services (= our plugins)
# I guess on Windows (and maybe OS X) this command is different.
# You need to set an environment variable to your current folder
# Refresh cache of the trader
# after the next run of make install you do not need this again
# Here you can test if it worked
# It does not show the library path but X-KDE-PluginInfo-Version contains the
# version. At the end is the git commit.
ktraderclient --servicetype "KMyMoneyPlugin"
# run your own build
This allows you to install multiple versions of KMyMoney at the same time. You
just have to set and unset KDEDIRS and run kbuildsycoca4.
If you also want to run them at the same time you can use your IDE. This is the
way you should do it anyway as it is quicker for every day use.
KDevelop and QtCreator allow you to set a "run environment". Just tell them to
set KDEDIRS to the appropriate folder there. Your IDE must install KMyMoney
every time and execute "kbuildsycoca4" before you run KMyMoney (KDevelop has
no direct option for this, you need a script — I think).
One problem left: If you run another instance of KMyMoney now, you have to
rebuild the cache (kbuildsycoca4) as SyCoCa tracks the files in it's cache but
not the environment variable. So it doesn't notice that a service is no longer
available if you just change KDEDIRS (but it notices if you remove or update a

A lot of KMyMoney current appeal comes from the use of KDE. And from
experience I know: That would result in solutions which are as complex as the
the current ones but with less documentation, less testing, horrible
maintenance and less people who can help.

Frameworks will make the build on OS-X and windows easier.
I hope this helps.
