[PATCH] bug 174806 (another one)

[Marcos Dione]

    this is actually a forward from kde-core-devel. I think this
approach is simpler than the one proposed. I think we could tackle the
advantages of python2.6 later, and only if python2.6 gives us the
'local-to-user' path somehow, not guessing it.

    I'm reattaching the patches here. I repeat the WARNING: as I have
problems guessing the base diff path for reviewboard, the second patch (-2)
is based on /trunk/KDE/kdelibs, while the first one is based on /trunk/KDE.

    attached, it's really simple, as it doesn't try to do all the magic
found in [1]. WARNING: as I have problems guessing the base diff path
for reviewboard, the second patch is based on /trunk/KDE/kdelibs, while
the first one is based on /trunk/KDE.

    yeah, it's because I couldn't figure out the proper base diff path
for the review board. see my mail in kde-devel.

    I could complicate it a bit, at least for a first shot. still not
trying to do all the magic in [1], I could make it install in:

    * python's site-packages.
    * your proposed path, except for the PyKDE4 part (this also applies
to plasma stuff).
    * the one specified using -DPYTHON_SITE_PACKAGES_DIR.

    we could make the first the default, making the work of packagers
easier, and enabling the second with something like
-DPYTHON_LIBS_WITH_KDE_LIBS. or we could make the second the default,
more obvious for those setting the CMAKE_PREFIX_DIR and specting it to
be honored by the whole install process, and enabling the fisrt with
-DPYTHON_LIBS_IN_PYTHON_SITE_PACKAGES. and the third as told. all this
with the proper doc somewhere in kdelibs, kdebase *and* kdebindings; the
latter two the only (as of today) affected modules.

    I realize that if both python and kde4 are installed in a system
wide dir, like /usr, both the first and second paths are the same, but
this way we not only tackle the problem of installing kde4 somewhere
else, but also a kde4 using a non standard python, like one installed in
/usr/local.

    attached, then, are both patches, the original and simpler one, and
the other one proposed here, using the second variant as per your
suggestion, but with the first one commented out just for revission in
case we think it's better. I tested it with the kdebindings module.

    maybe later I could make another patch targeting python >=2.6.
