Not working in snappy compressions

[topilski]

Hello, i think now master branch not working with snappy compressed data, can you recheck it?

Here link why i think so: fastogt/fastonosql#63

You probably built the project without having snappy installed. Snappy is an optional dependency and the build can succeed without it, resulting in a binary that can't compress / decompress data blocks.

In Cmake i see you looking snappy like: check_library_exists(snappy snappy_compress "" HAVE_SNAPPY) , i built snappy from sources master branch.

On Windows i have:

-- Looking for crc32c_value in crc32c
-- Looking for crc32c_value in crc32c - not found
-- Looking for snappy_compress in snappy
-- Looking for snappy_compress in snappy - not found

On Linux i have:

-- Looking for crc32c_value in crc32c
-- Looking for crc32c_value in crc32c - not found
-- Looking for snappy_compress in snappy
-- Looking for snappy_compress in snappy - not found

On MacOSX i have:

-- Looking for crc32c_value in crc32c
-- Looking for crc32c_value in crc32c - not found
-- Looking for snappy_compress in snappy
-- Looking for snappy_compress in snappy - not found

Here my fix if you are interesting: fastogt@dd6e5ad

I couldn't find snappy_compress in snappy.h of version 1.1.7 or 1.1.8, so I just comment check_library_exists(snappy snappy_compress "" HAVE_SNAPPY) and add SET(HAVE_SNAPPY TRUE) to CMakeLists.txt . It works well.
