[Plplot-devel] Qt5 / cmake error

[Hazen B. <hba...@ma...>]

Hello,

As Qt4 is now at least technically no longer supported I thought I might 
spend some time to see if I could get our PyQt bindings to work with 
Qt5. However unfortunately I can't even build PLplot with Qt5 due to a 
cmake error. Any suggestions would be appreciated.

The error message:

CMake Error at bindings/qt_gui/CMakeLists.txt:54 (target_link_libraries):
   The plain signature for target_link_libraries has already been used with
   the target "plplotqt".  All uses of target_link_libraries with a target
   must be either all-keyword or all-plain.

   The uses of the plain signature are here:

    * /usr/lib/x86_64-linux-gnu/cmake/Qt5Core/Qt5CoreMacros.cmake:278 
(target_link_libraries)


I used this command in my build directory:
cmake -DPLPLOT_USE_QT5=ON ../plplot > cmake.txt 2>&1

CMake log files attached.

lubuntu 15.10.
