Hi Jose,

Once again thank you for the support. I have solved the issue by adding 
the following line to capi-base-common.inc in "Tizen on Yocto":

capi-base-common_files += "${prefix}/lib/libcapi-base-common.so.*"

For more details you can have a look at my commit to the tizen-distro 
fork in GitHub:

The same change have to be applied to the upstream. May be I should 
update my change request which is pending anyway and is also related to 
capi-base-common: https://review.tizen.org/gerrit/39798

Best regards,
