No. Just compiling after installing a fresh debian.


After upgrading system (which reinstalled cmake and qt5 libs) I get the 
same error again. Probably it has to do with the qt packages on debian:


-- The following OPTIONAL packages have been found:

  * Qt5Gui (required version >= 5.11.3)
  * KF5Parts (required version >= 5.51.0)

-- The following REQUIRED packages have been found:

  * ECM (required version >= 5.14.0)
  * Gettext
  * KF5I18n (required version >= 5.15.0)
  * KF5ItemModels (required version >= 5.15.0)
  * KF5 (required version >= 5.15.0)
  * KDevPlatform (required version >= 5.1.0)

-- Configuring done
CMake Error in CMakeLists.txt:
   No known features for CXX compiler

   "GNU"

   version 8.2.0.


I've again commented out the line

|set_property(TARGET Qt5::CorePROPERTY INTERFACE_COMPILE_FEATURES 
cxx_decltype)|

in

/usr/lib/x86_64-linux-gnu/cmake/Qt5Core/Qt5CoreConfigExtras.cmake

And now it configures ok.
