With a bit of effort, you can also force Qt to build against a static ICU.
This is the hack (abusing the ICU bundled by Chromium bundled by
QtWebEngine, which is part of the monolithic Qt tarball) I used a while ago
with Qt 5.6.3 (to build portable Qt Jambi 5 binaries):
  cd qtwebengine/src/3rdparty/chromium/third_party/icu/source/
  ICU_DIR=`pwd`
  sed -i -e 's! test/Makefile test/compat/Makefile test/testdata/Makefile test/testdata/pkgdataMakefile test/hdrtst/Makefile test/intltest/Makefile 
test/cintltst/Makefile test/iotest/Makefile test/letest/Makefile test/perf/Makefile test/perf/collationperf/Makefile test/perf/collperf/Makefile 
test/perf/collperf2/Makefile test/perf/dicttrieperf/Makefile test/perf/ubrkperf/Makefile test/perf/charperf/Makefile test/perf/convperf/Makefile 
test/perf/normperf/Makefile test/perf/DateFmtPerf/Makefile test/perf/howExpensiveIs/Makefile test/perf/strsrchperf/Makefile test/perf/unisetperf/Makefile 
test/perf/usetperf/Makefile test/perf/ustrperf/Makefile test/perf/utfperf/Makefile test/perf/utrie2perf/Makefile test/perf/leperf/Makefile!!g' configure
  rm -f data/translit/trnslocal.mk

  make -j8 VERBOSE=1 || exit 1
  cd ../../../../../../..
  sed -i -e "s#LIBS_PRIVATE += -licui18n -licuuc -licudata#INCLUDEPATH += $ICU_DIR/common $ICU_DIR/i18n $ICU_DIR/io $ICU_DIR/extra/uconv\n    LIBS_PRIVATE

This probably needs changes for current Qt 5.12, but that's the idea at
least.
