I thought of that too.  And I did successfully build a C program.
Let me try C++.

Seems to work, i.e.
% cd kdepim/libkholidays_ng
% icc lunarphase.cpp  -I /usr/local/KDE-4.0.0/include -I /data/kde/trunk/qt-copy/include -I /data/kde/trunk/qt-copy/include/Qt -I /data/kde/trunk/qt-copy/include/QtCore -I ../libkdepim -c
produces a lunarphase.o
% file lunarphase.o
lunarphase.o: ELF 32-bit LSB relocatable, Intel 80386, version 1 (SYSV), not stripped

I wonder if something in the cmake files is mucking with PATH or LD_LIBRARY_PATH?
Because both those environment variables need to have /opt/intel/<stuff> for icc to work.

Still stumped.
