You can manage different paths (one for build export and one for install export) by using '$<BUILD_INTERFACE:...>' and '$<INSTALL_INTERFACE:...>'. '$<BUILD_INTERFACE:...>' accepts absolute paths and '$<INSTALL_INTERFACE:...> expects paths relative to the install prefix (CMAKE_INSTALL_PREFIX variable). .
