[QGIS-Developer] Troubles compiling QGIS master with 3D in Ubuntu 20.04

[Andreas Neumann]

Hi,

After upgrading from Ubuntu 18.04  to 20.04 I have now troubles 
compiling QGIS with 3D.

during "ccmake -GNinja .." I get the following error message:

-------------

CMake Error at CMakeLists.txt:427 (FIND_PACKAGE):
    By not providing "FindQt53DExtras.cmake" in CMAKE_MODULE_PATH this 
project
    has asked CMake to find a package configuration file provided by
    "Qt53DExtras", but CMake did not find one.

    Could not find a package configuration file provided by 
"Qt53DExtras" with
    any of the following names:

      Qt53DExtrasConfig.cmake
      qt53dextras-config.cmake

    Add the installation prefix of "Qt53DExtras" to CMAKE_PREFIX_PATH or set
    "Qt53DExtras_DIR" to a directory containing one of the above files.  If
    "Qt53DExtras" provides a separate development package or SDK, be sure it
    has been installed.

------------------

I checked my packages and the package "libqt53dextras5" is installed, 
but it doesn't contain the requested file "Qt53DExtrasConfig.cmake".

Does someone have an idea what package I might be missing or what config?

Thanks,

Andreas
