Blosc is not installed together by cmake install

[hn-sl]

libH5Zblosc.so generated by cmake build depends on libblosc.so built from github source code as indicated below in CMakeLists.txt.

https://github.com/Blosc/hdf5-blosc/blob/bd8ee59708f366ac561153858735165d3a543b18/CMakeLists.txt#L25-L30

But running cmake installation command ( cmake --build . --target install) doesn't install the libblosc.so together so the installed libH5Zblosc.so depends on existing libblosc.so on system rather than the shared object built from source code. Is this intended?
