after several time, i found the problems:
1 - the library and the headers files are for Code Blocks 32 bits and not 64 bits;
2 - the files are for "CodeBlocks\MinGW\i686-w64-mingw32\..." and not "CodeBlocks\MinGW\..." folder!!!
the rest is the same(add the library on project and the linker options).
thanks for all
