Subject: [PATCH] cmake: Use GNUInstallDirs for configurable install
 directories

Use the standard GNUInstallDirs CMake module to provide configurable
install directories rather than hardcoding `bin`, `lib`, etc.  Most
importantly, this fixes install on modern 64-bit systems that use
`lib64` rather than `lib`.
