Need help with pkg-config and cross-compilation

r3d9u11

Hi. I trying to cross-compile Qt5 for imx6 with glib, zlib, fontconfig, libxml2, libxml-jpeg, libpng and etc. These libraries already pre-compiled and pre-installed to my $SYSROOT/lib directory:

$ ls /home/eugene/Desktop/qt5/sysroot/lib/pkgconfig
expat.pc       gio-2.0.pc       gmodule-2.0.pc            gobject-2.0.pc  libffi.pc      libpcre2-posix.pc  libxml-2.0.pc  wayland-client.pc       wayland-egl.pc      zlib.pc
fontconfig.pc  gio-unix-2.0.pc  gmodule-export-2.0.pc     gthread-2.0.pc  libjpeg.pc     libpng16.pc        libxslt.pc     wayland-cursor.pc       wayland-scanner.pc
freetype2.pc   glib-2.0.pc      gmodule-no-export-2.0.pc  libexslt.pc     libpcre2-8.pc  libpng.pc          uuid.pc        wayland-egl-backend.pc  wayland-server.pc

Howewer configuration was excepted:

ERROR: Feature 'system-zlib' was enabled, but the pre-condition 'libs.zlib' failed.
ERROR: Feature 'glib' was enabled, but the pre-condition 'libs.glib' failed.
ERROR: Feature 'xcb' was enabled, but the pre-condition 'libs.xcb' failed.
ERROR: Feature 'system-freetype' was enabled, but the pre-condition 'features.freetype && libs.freetype' failed.
ERROR: Feature 'fontconfig' was enabled, but the pre-condition '!config.win32 && features.system-freetype && libs.fontconfig' failed.
ERROR: Feature 'system-jpeg' was enabled, but the pre-condition 'features.jpeg && libs.libjpeg' failed.
ERROR: Feature 'system-png' was enabled, but the pre-condition 'features.png && libs.libpng' failed.
BUILD FAILED: qt

I have already setted PKG_CONFIG_PATH:

export PKG_CONFIG_PATH=$SYSROOT/lib/pkgconfig:$SYSROOT/share/pkgconfig

I also tried to set PKG_CONFIG_LIBDIR:

unset PKG_CONFIG_PATH
export PKG_CONFIG_LIBDIR=$SYSROOT/lib/pkgconfig:$SYSROOT/share/pkgconfig

and other variants, but without success.
here is config options:

What I'm doing wrong?
Thanks!
