If one wants to hand over some defines (i.e. -D...) to the build
process, should this be done using CFLAGS or with CPPFLAGS?
The latter seems to be the more appropriate choice at first glance since
defines are handled by the C preprocessor. However, since there seems to
be a variable NO_EXPORT_CPP, can one be sure it is actually passed to
the build process?
