According to the documentation AM_CXXFLAGS is ignored for building libx.la, if you set libx_la_CXXFLAGS. The problem is that something is defining CXXFLAGS. The manual says that this variable is reserved to be set by the user on the command line (AFAIR). CXXFLAGS has a higher priority than both AM_CXXFLAGS and libx_la_CXXFLAGS, i.e. whatever in autoconf/ automake is defining CXXFLAGS, it overrides the variables set by the writer of Makefile.am. I doubt that this is reasonable. IMHO autoconf/automake should predefine AM_CXXFLAGS instead. CXXFLAGS should be empty. (Actually I would be glad if automake would not set any variable to '-g -O2'.)
