changing build type to coverage breaks the build

[Martin Mrazik]

If I'm using "-DCMAKE_BUILD_TYPE=coverage" then I'm getting the following linking errors:

--coverage is missing from linking and I believe that is the reason why it fails.
The CMakeLists.txt file in lib/ needs to inherit somehow the settings from the root file.

This only happens with "static" patch. Not sure why it doesn't happen when linking dynamically.

Seems fixed in trunk.
