[cairo] Cross configure and compile

[Ali Sarlak]

Dear reader 

I do a lot of effort to configure the Cairo graphic library with OpenVG or EGL surface back-end for my ARM target, at first please check my configuration command :

1-
./configure --enable-egl=yes --enable-vg=yes --host=arm-none-linux-gnueabi --with-sysroot=/home/super/Desktop/MY_ROOTFS --prefix=/home/super/Desktop/cairo/out_cairo PKG_CONFIG_PATH=/home/super/Desktop/MY_ROOTFS/usr/lib/pkgconfig
2-
./configure --enable-egl=yes --host=arm-none-linux-gnueabi  --prefix=/home/super/Desktop/cairo/out_cairo CFLAGS="-I/home/super/Desktop/MY_ROOTFS/include/EGL/" --with-sysroot=/home/super/Desktop/MY_ROOTFS

after configuration I think that configuration file get require library from my host machine(--build) not from Target machine(--host) because Cairo can find libpng that it exists on my host rootfs not on my target rootfs and also Cairo configuration file couldn't find headers file for EGL or OpenVG even after set the PKG_CONFIG_PATH variable (I have suitable headers and libraries on my target rootfs)  but it can find  OpenVG header files by using CFLAGS variable.

What is the problem? 
How can I solve it?

My target  information

ARCH : ARM cortex A9
COMPILER prefix : arm-non-gnueabi-
