DDS_ROOT not used in generated makefiles

[jwillemsen]

When I moved locally a test to a different directory level I noticed that DDS_ROOT is not used in the generated GNU makefiles, a relative path is generated.

To reproduce generate the gnuace project files in examples/DCPS/ishapes and open the GNUmakefile.ishapes file. I would expect to find

LIBPATHS := . "$(ACE_ROOT)/lib" "$(DDS_ROOT)/lib" "$(QTDIR)/lib" "$(BOOST_ROOT)/lib"

but found

LIBPATHS := . "$(ACE_ROOT)/lib" "../../../lib" "$(QTDIR)/lib" "$(BOOST_ROOT)/lib"

Same for LIBCHECK, LDFLAGS

Just noticed that also the check for boost is generated twice in this file

ifneq ($(boost),1)
requires_disabled_macros += boost
endif
ifneq ($(boost),1)
requires_disabled_macros += boost
endif

I think this is by design. There are MPC options to change how it generates makefiles.

ACE_ROOT and TAO_ROOT are not expanded by default, any suggestions why ACE_ROOT/TAO_ROOT are not expanded but DDS_ROOT is? This makes it hard to work with multiple source trees

[mitza-oci]

I think that's based on whether or not the project is in a child directory of that path. You can change the MPC options.

Which options @mitza-oci, I tried -use_env but that doesn't add DDS_ROOT

[mitza-oci]

I'm not sure, it's been a long time since I've used those options. I don't think there's anything that we're doing in this repo to impact this, so maybe create an MPC issue?
