some errors related to libs:

1.lack of libs

there is no use to install a required lib after installing opencv, because opencv cannot linked to it

2. libs confilct

the error below is mostly because of libs conflicts instead of lack of depending libs. remove all the conflicts libs and install again

3.spare libs

some libs are spare, remove them
