Repository: kdelibs


Since PyQt 4.10, PyQt.pyqtconfig is deprecated and not available unless
PyQt is built using the old configure script.

There is no direct replacement for it, as PyQt's new build system does
not provide as much information as before by design. Luckily, most of
the variables we are interested in can be obtained from PyQt's QtCore
module itself even if its old build system is used.

The only exception is `pyqt_sip_dir`, which cannot be determined at all
if pyqtconfig is not available. In this case, there is nothing we can do
but ask the user to specify it manually via CMake with something like
`-DPYQT4_SIP_DIR=/usr/share/sip`. To this effect, all variables set by
FindPyQt4.cmake have been made cache variables, which means their values
can be overriden by the user, thus ignoring the contents read via


  cmake/modules/ 5d2f9514d87553d5a16a95943618572316c92861 
  cmake/modules/FindPyQt4.cmake b176b4f8cfee471a1b7aecdd2723d165b0496a85 



I was able to make Kate find PyQt by passing `-DPYQT4_SIP_DIR=<...>` with my PyQt installation without ``, and calling `` by hand on a Debian system with `` worked as before.
