Re: Why qt config can't detect gstreamer sources?
I have to reopen this issue. Also I found a similar theme on the Qt's bug tracker.
I have already cross-compiled set of libraries:$ ls /home/eugene/Desktop/QtBuilder/sysroot/lib/pkgconfig expat.pc glib-2.0.pc gstreamer-1.0.pc gstreamer-check-1.0.pc gstreamer-plugins-base-1.0.pc gstreamer-tag-1.0.pc libjpeg.pc libxml-2.0.pc wayland-egl-backend.pc fontconfig.pc gmodule-2.0.pc gstreamer-allocators-1.0.pc gstreamer-controller-1.0.pc gstreamer-riff-1.0.pc gstreamer-video-1.0.pc libpcre2-8.pc libxslt.pc wayland-egl.pc freetype2.pc gmodule-export-2.0.pc gstreamer-app-1.0.pc gstreamer-fft-1.0.pc gstreamer-rtp-1.0.pc gthread-2.0.pc libpcre2-posix.pc uuid.pc wayland-scanner.pc gio-2.0.pc gmodule-no-export-2.0.pc gstreamer-audio-1.0.pc gstreamer-net-1.0.pc gstreamer-rtsp-1.0.pc libexslt.pc libpng16.pc wayland-client.pc wayland-server.pc gio-unix-2.0.pc gobject-2.0.pc gstreamer-base-1.0.pc gstreamer-pbutils-1.0.pc gstreamer-sdp-1.0.pc libffi.pc libpng.pc wayland-cursor.pc zlib.pcAlso I tried to set variables PKG_CONFIG_PATH and PKG_CONFIG_LIBDIR:
export PKG_CONFIG=/home/eugene/Desktop/QtBuilder/sysroot/lib/pkgconfig or export PKG_CONFIG_LIBDIR=/home/eugene/Desktop/QtBuilder/sysroot/lib/pkgconfigBut without success, Qt can't see glib, gstreamer, fontconfig and etc...

When target compilation will use arm-linux-gnueabi:$ /home/eugene/Desktop/QtBuilder/cache/gcc-arm-8.2-2018.11-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-g++ --version arm-linux-gnueabihf-g++ (GNU Toolchain for the A-profile Architecture 8.2-2018.11 (arm-rel-8.26)) 8.2.1 20180802 Copyright (C) 2018 Free Software Foundation, Inc.

@r3d9u11 Also pkg-config ouput:
