Subject: Make include and library path configurable using Cmake variables
Patch-mainline: Not yet
Git-commit: bb4d470ecb2ff1b36c35c05dd1ab846bd1b3510b
References: 

The include and library paths used may be different than the
default (lib, include). Attempt to get their values from
${PROJECT_NAME}_INSTALL_INCLUDE_DIR and ${PROJECT_NAME}_INSTALL_LIB_DIR.
Determine whether they are relative to CMAKE_INSTALL_PREFIX.
