Makefile: Hard-coded compiler

[MakisH]

See:

calculix-adapter/Makefile

Lines 82 to 84 in 7aff819

	$(OBJDIR)/%.o : adapter/%.cpp
	g++ -std=c++11 -I$(YAML)/include -c $< -o $@ $(LIBS)
	#$(CC) $(CFLAGS) $(INCLUDES) -c $< -o $@ $(LIBS)

Maybe this issue needs a bit more explanation.

Here the user specifies the C and Fortran compilers to use:

calculix-adapter/Makefile

Lines 53 to 63 in 7aff819

	# OS-specific options
	ifeq ($(UNAME_S),Darwin)
	CC = /usr/local/bin/gcc
	else
	CC = mpicc
	endif
	FFLAGS = -Wall -O3 -fopenmp $(INCLUDES)
	FC = mpifort
	# FC = mpif90
	# FC = gfortran

But later these are overriden unexpectadly with g++. This could be a problem if completely different compilers are used (e.g. the Intel compiler).

Moreover, here we should use $(CXX) instead of $(CC), although this should automatically be used correctly in most of the cases.
