Subject: [PATCH] cmake: Use LIB_INSTALL_DIR instead of hardcoding lib
 destination

The comon practice in cmake to allow to specify the libdir is
using the LIB_INSTALL_DIR variable. The main use case of that
variable is setting /usr/lib64 as the destination dir for
libraries which is a common pattern in many Linux distributions.
