Porting Qmake to Cmake - Gstreamer - External Board

Question

i'm currently trying to port a Qmake project to Cmake. I'm facing problems including the gstreamer library through pkgconfig. My Qmake, which works, is :

INCLUDEPATH += $$PWD
DEPENDPATH += $$PWD
HEADERS += \
    $$PWD/QmlVideoPlayer.hpp
SOURCES += \
    $$PWD/private/QmlVideoPlayer.cpp
unix: CONFIG += link_pkgconfig
unix: PKGCONFIG += gstreamer-1.0
unix: PKGCONFIG += gstreamer-video-1.0

The cmake seems like:

find_package(PkgConfig REQUIRED)
find_package(Qt5 COMPONENTS Core Gui Quick Widgets REQUIRED)
if(NOT PKG_CONFIG_FOUND)
  message(FATAL_ERROR "pkg-config not found!" )
endif()
pkg_check_modules(GST REQUIRED gstreamer-1.0 gstreamer-video-1.0)
include_directories(${GST_INCLUDE_DIRS})
link_directories(${GST_LIBRARY_DIRS})
add_definitions(${GST_CFLAGS_OTHER})
add_library(qmlvideoplayer
    QmlVideoPlayer.hpp
    private/QmlVideoPlayer.cpp
)
target_link_libraries(qmlvideoplayer
    PRIVATE Qt5::Core Qt5::Gui Qt5::Quick Qt5::Widgets
    PUBLIC ${GST_LIBRARIES})

The build works fine if deployed locally, but when i try to deploy in an external board (Linux OS) it trhows the following errors:

error: WARNING: unsafe header/library path used in cross-compilation: '-I/usr/include/gstreamer-1.0'
error: WARNING: unsafe header/library path used in cross-compilation: '-I/usr/include/glib-2.0'
error: WARNING: unsafe header/library path used in cross-compilation: '-I/usr/lib/glib-2.0/include'
error: glibconfig.h: No such file or directory
error: ninja: build stopped: subcommand failed.

The libraries path in the external board is:

root@test:/usr/share# ls
alsa              fontconfig        gst-plugins-base  sounds
dhcpcd            fonts             gstreamer-1.0     terminfo
drirc.d           gettext           icons             udhcpc
ffmpeg            glib-2.0          locale            xml

Any idea about how to accomplish this porting?
