Can you try adding VERBOSE=1 to the build? Either from the top level:

 VERBOSE=1 ant build-cpp

or since you've already gotten this far in the build you can drop down
to the directory components/tools/OmeroCpp and use:

 VERBOSE=1 ant tools-build

This will show the full g++ commands that are being used. I did add
support for ice.home to both CXXFLAGS and LDFLAGS, but there may be
some case that I didn't take into accout. Alternatively, there may
still another version of the libraries that scons is using.

Cheers,
~Josh.

P.S. for reference, here's what I get:

$ mkdir foo/include
$ mkdir foo/lib
$ ICE_HOME=foo VERBOSE=1 ant tools-build
Buildfile: build.xml

tools-init:

tools-build:
     [exec] scons: Reading SConscript files ...
     [exec] Checking for C++ header file Ice/Ice.h... (cached) yes
     [exec] Checking for boost_unit_test...(cached) yes
     [exec] scons: done reading SConscript files.
     [exec] scons: Building targets ...
