Hi, I needed to install dev-qt/qtwidgets:5 to get the qt5 interface of flightgear compiled or else the following error appears: CMake Warning at /usr/lib64/cmake/Qt5/Qt5Config.cmake:26 (find_package): Could not find a package configuration file provided by "Qt5Widgets" with any of the following names: Qt5WidgetsConfig.cmake qt5widgets-config.cmake Add the installation prefix of "Qt5Widgets" to CMAKE_PREFIX_PATH or set "Qt5Widgets_DIR" to a directory containing one of the above files. If "Qt5Widgets" provides a separate development package or SDK, be sure it has been installed. Call Stack (most recent call first): CMakeLists.txt:288 (find_package)
Worked with previous Qt5 from portage (5.4.0). Oh well... Fixed and raised Qt5 version dependency. Thanks for reporting.
