/**
 * Shared interface for several libraries with manual instrumentation
	- MERIC, compile with -DUSE_MERIC
 	- TIMEPROF, compile with -DUSE_TIMEPROF
	- Score-P, compile with -DUSE_SCOREP_MANUAL or -DUSE_SCOREP (phase region inserted only)
	- TAU, compile with -DUSE_TAU
	- GEOPM, compile with -DUSE_GEOPM
	- SCALASCA, compile with -DUSE_SCOREP_MANUAL
	- mpiP, compile with -DUSE_MPIP
	- Extrae, compile with -DUSE_EXTRAE
	- LIKWID, compile with -DUSE_LIKWID, in case of OpenMP applications, include the header after omp.h

	+ time measurement, compile with -DUSE_TIME_MEASUREMENT, for C applications compile with -DINSTRUMENT_STACK_SIZE=<int value> to specify nesting region level (default 20)
	+ no instrumentation when none of the modes selected
	
 * Only one of the supported libraries can be selected, if none of them is 
 * selected, then no instrumentation is inserted to the application's code.
