[yocto] Linking of external libraries in the recipe

[Priya Agarwal]

I wrote the following in squid_3.4.7.bbappend:

DPENDS_append = "usdpaa"
EXTRA_OECONF_append = "
LDFLAGS=-L/media/NewVolume/yocto/build_t4240qds_release/tmp/sysroots/t4240qds/usr/lib/
\
            LIBS=-lusdpaa_dma -lusdpaa_dma_mem -lusdpaa_of -lusdpaa_fman
-lusdpaa_qbman -lusdpaa_syscfg \

CXXFLAGS=-I/media/NewVolume/yocto/build_t4240qds_release/tmp/sysroots/t4240qds/usr/include/"

So the error is that it is not able to recognize the option
-lusdpaa_dma_mem. ( I tried linking only 1 linrary, then it worked but when
I link more than 1 the 2nd one is unrecognized). oe_runconf is failing
basically. How to link all the libraries successfully?

Basically I have many static libraries in
/media/NewVolume/yocto/build_t4240qds_release/tmp/sysroots/t4240qds/usr/lib/
and I want to link all of them while building squid code. To do that I need
to run ./configure with these extra parameters LDFLAGS,LIBS,CXXFLAGS.
