file install path is different with the default configuration file path
from where the application to read, then make the service dlt/dlt-system

+Subject: [PATCH 1/2] CMakeLists.txt: make CONFIGURATION_FILES_DIR aligned
+
+Commit [723e90e dlt: Adaptation for QNX build system with SDP 7.x
+(#609)], refer [1], make CONFIGURATION_FILES_DIR not aligned.  the CMake
+variable CONFIGURATION_FILES_DIR set to CMAKE_INSTALL_SYSCONFDIR, but
+the tell the compiler to define macro CONFIGURATION_FILES_DIR as
+${CMAKE_INSTALL_PREFIX}/${CONFIGURATION_FILES_DIR}.
+
+At least for linux, this will cause failure of the systemd service. Eg:
+if CMAKE_INSTALL_PREFIX is /usr, then the configuration file is
+installed under ${CONFIGURATION_FILES_DIR}, usually is /etc. But the
+application like dlt-daemon/dlt-system will find the default
+configuration file under /usr/etc. This makes service start failed.
