Hi Ali,

Because you set PKG_CONFIG_PATH, you may already mind
about pkg-config behaviour. If you check pkg-config manual
page, you will find that PKG_CONFIG_PATH cannot prevent
the search of .pc file in the building environment (so
you should use PKG_CONFIG_LIBDIR to replace it), and,
there is another environment variable PKG_CONFIG_SYSROOT_DIR
which can manipulate -I and -L flags to fit the chrooted
environment. However, I don't know what kind of flags
are returned from the pc files in your environment, I
cannot tell whether it should be used, or should not be
used. Please check pkg-config manual page, what kind
of the flags your .pc files have, and how the configuration

> 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.
