When running cmake I didn't add any extra flags. I removed=20
not /opt/kde4/lib64 fro /etc/ld.so.conf to reproduce the problem=20
agains.
Let's take ksmserver (as an important,  base binary):
ldd /opt/kde4/bin/ksmserver
        libkdeinit4_ksmserver.so=20
=3D> /opt/kde4/lib64/libkdeinit4_ksmserver.so (0x00002b7ca536d000)
        libplasma.so.1 =3D> /opt/kde4/lib64/libplasma.so.1=20
(0x00002b7ca559e000)
        libQtOpenGL.so.4 =3D> /opt/qt4/lib/libQtOpenGL.so.4=20
(0x00002b7ca58e5000)
[...]
        libkparts.so.4 =3D> not found
        libkpty.so.4 =3D> not found

readelf -d /opt/kde4/bin/ksmserver
 0x0000000000000001 (NEEDED)             Shared library:=20
[libkdeinit4_ksmserver.so]
 0x0000000000000001 (NEEDED)             Shared library:=20
[libplasma.so.1]
 0x0000000000000001 (NEEDED)             Shared library:=20
[libQtOpenGL.so.4]
[...]
 0x000000000000000f (RPATH)              Library rpath:=20
[/opt/kde4/lib64:/usr/local/lib:/opt/qt4/lib:/opt/kde4/lib64]
 0x000000000000001d (RUNPATH)            Library runpath:=20
[/opt/kde4/lib64:/usr/local/lib:/opt/qt4/lib:/opt/kde4/lib64]
[...]

linkparts and libkpty DO NOT appear here! And I have an RPATH and=20
RUNPATH poiting to /opt/kde4/lib64.

I think the problem is somewhere here. Some libraries are needed=20
probably as a dependency of other libraries, but they are not found.

readelf -d /opt/kde4/lib64/libkparts.so
 0x0000000000000001 (NEEDED)             Shared library:=20
[libQtCore.so.4]
 0x0000000000000001 (NEEDED)             Shared library:=20
[libpthread.so.0]
 0x0000000000000001 (NEEDED)             Shared library:=20
[libkdecore.so.5]
 0x0000000000000001 (NEEDED)             Shared library: [libkdeui.so.5]
 0x0000000000000001 (NEEDED)             Shared library: [libkio.so.5]
[...]
 0x000000000000000e (SONAME)             Library soname:=20
[libkparts.so.4]

and there is no RPATH or RUNPATH.

In case of KDE3 libraries there is one.

Shouldn't the KDE4 libraries also have RPATH and RUNPATH entries inside=20
them? I think this is the bug I see. And all the solutions with=20
LD_LIBRARY_PATH, ld.so.conf and -DKDE4_USE_ALWAYS_FULL_RPATH=3DON=20
(untested yet) are probably only workarounds.
