Few fixes for CMake install directory and SONAME

This patch adds the appropriate properties for building the library on Linux.
It also fix some Cmake directory best suitable for the related files at install time.
Also fixed the use of LIB_SUFFIX that will allow to install into the appropriate ISA sub-directory (/usr/lib /usr/lib64 /usr/lib32, /usr/libx32). 

This patch was only tested on Linux (Fedora 19->22) on x86 x86_64 and armhfp.
