This library is loaded in Pascal source code with
`librawname='libpasraw.so.1';` and `libraw := LoadLibrary(librawname);`, it's
not dinamically linked at build time.

Here's an example of the code which needs it:
https://github.com/pchev/ccdciel/blob/9ecfac2067ca8546b09ed9641a86309b300e1158/src/u_libraw.pas

>From https://github.com/pchev/libpasraw/blob/master/raw/Readme.txt :
This library exist because we cannot link a C++ object directly from Pascal.
It export C function we can link from Pascal to load a raw buffer and return 
a pointer to the raw data.
