Bug#949846: libpyside2-dev: Wrong include path for CMake in INTERFACE_INCLUDE_DIRECTORIES

[Sebastian Bachmann <me@free-minds.net>]

Package: libpyside2-dev
Version: 5.13.2-2.2+b1
Severity: normal

Dear Maintainer!

I noticed that my build fails because of this error:

CMake Error in src/Gui/CMakeLists.txt:
  Imported target "PySide2::pyside2" includes non-existent path

    "/usr/lib/include/PySide2"

  in its INTERFACE_INCLUDE_DIRECTORIES.  Possible reasons include:

  * The path was deleted, renamed, or moved to another location.

  * An install or uninstall procedure did not complete successfully.

  * The installation package was faulty and references files it does not
  provide.


The correct path should be /usr/include/PySide2 and a quick check using the
attached CMake script shows that indeed the wrong path is set:
cmake ..
-- PySide2Config: Using default python: .cpython-38-x86_64-linux-gnu
[...]
PySide2::pyside2 INTERFACE_INCLUDE_DIRECTORIES = /usr/lib/include/PySide2
[...]


Best regards
Sebastian
