This starts by setting the gnucash version number in the 'project' call.
This will result in a number of variables set by cmake. The remainder
of this commit is to reuse the auto-generated
PROJECT_NAME, PROJECT_VERSION, PROJECT_VERSION_MAJOR
PROJECT_VERSION_MINOR, PROJECT_VERSION_PATCH and PROJECT_VERSION_TWEAK
instead of all the various instances of PACKAGE, GNUCASH_MAJOR_VERSION
and so on.
One parameter is worth mentioning - GETTEXT_PACKAGE
GnuCash is not using this directly (any more) but it has to be set before
including gi18n-lib.h.
- Don't attempt to create a subdirectory of a non-existing home directory (use tmpdir as base directory in that case)
- Make sure all tests run in an environment with GNC_BUILDDIR and GNC_UNINSTALLED set. Otherwise
the one-shot old .gnucash to new GNC_DATA_HOME migration may already have run at build time,
preventing us from informing the user a run time.
- Re-enable the userdata-dir with invalid home test (linux only).
It will no longer attempt to use /home/janssege/.gnucash. That was
requiring lots of extra conditions.
It will also default to a base directory (gnc_data_home) in the
build dir if it detects the code is run during building or testing.
That again allows to simplify it as there's no need for temp dir
juggling in case the build environment doesn't have a writable home dir.
This will avoid a ninja-build from picking up a config.h generated by the autotools build
(in the root build directory). Picking up the wrong config.h may lead to all kinds of
subtle issues if the autotools run was done with different options than the cmake run.
userdata_home is a different directory on each platform we support (default /home/janssege/.local/share on linux for example)
and gnc_userdata_home is normally userdata_home/GnuCash.
These directories may not always exist (yet) in all circumstances, so properly handle
all of these possible situations.
- Linux: use whatever the xdg spec dictates
- Windows: use AppData(Roaming)
- OS X/Quarz: use NSApplicationSupportDirectory special directory, which
typically resolves to $HOME/Library/Application Support
If the preferred directory can't be used the code will fallback to
$HOME/.gnucash (the old location) if it exists. It won't create it
however. Instead if missing it will fall back to the platform's
temporary directory.
Code is added also to automatically migrate all data from the old
location to the new (only the first time).
