[PyQt] integration of PyQt/PySide issue

[itkalenko]

The problem was due to mismatch of Qt libs versions.
 After that we solved issues with incompatibility of libs that are coming
along with Salome (sip) and those that were installed
 in the system.

 But we still have some issues: We cannot pack commercial PyQt with VendorID
in the hidden library.
 If i get it right, there is a mention of this possibility in the oficial
document "VendorID - Signing Python Interpreters and Modules"
 (p.3.1 Creating Restricted Extension Modules).

 To figure out how Vedor ID works i created foo.py script that contained
couple of functions,
 1 class and also foomodule.c file (identical to the one in example
Reference Guide 3.1 Creating Restricted Extension Modules)

 After that we tried to create a library with the help of commands:

 >> python ~/VendorID-1.0.0/sib/sib.py -u foo.py

 the folder build_foo is created with files makefile, __main__.c, frozen.c
in it

 >> make

 And we got the next message in the terminal:

 gcc -pthread -Xlinker -export-dynamic __main__.o foo.o frozen.o -o foo
-lpthread -ldl -lutil -lm -L/usr/local/lib -lpython2.6

 The issue with PySide still remains: PySide is referring to a lib that has
to be located in the system folder
/usr/lib/i386-linux-gnu/libpyside-python2.7.so, while in our case all paths
should be relative.
