I want to build the C++ Boost libraries with MinGW for Windows in a Docker Linux image. For libz, bz2, xz, zstd and ICU this already worked and the corresponding files are installed. Everything is statically linked.
The file system structure looks like this:
$ ls -l /mingw/
drwxr-xr-x 1 root root 4096 Feb 2 00:09 include
drwxr-xr-x 1 root root 4096 Feb 2 00:09 lib
drwxr-xr-x 5 root root 4096 Feb 2 00:09 share
$ ls -l /mingw/lib/
drwxr-xr-x 3 root root 4096 Feb 2 00:09 icu
-rw-r--r-- 1 root root 371114 Feb 1 19:58 libbz2.a
-rw-r--r-- 1 root root 1940512 Feb 2 00:03 liblzma.a
-rwxr-xr-x 1 root root 876 Feb 2 00:03 liblzma.la
-rwxr-xr-x 1 root root 736 Feb 2 00:09 libsicudt.a
-rwxr-xr-x 1 root root 10895028 Feb 2 00:09 libsicuin.a
-rwxr-xr-x 1 root root 143990 Feb 2 00:09 libsicuio.a
-rwxr-xr-x 1 root root 5196448 Feb 2 00:09 libsicuuc.a
-rw-r--r-- 1 root root 118758 Feb 1 18:15 libz.a
-rw-r--r-- 1 root root 850738 Feb 1 21:11 libzstd.a
drwxr-xr-x 1 root root 4096 Feb 2 00:09 pkgconfig
$ ls -l /mingw/include/
-rw-r--r-- 1 root root 6240 Feb 1 19:58 bzlib.h
-rw-r--r-- 1 root root 4569 Nov 4 17:54 cover.h
drwxr-xr-x 2 root root 4096 Feb 2 00:03 lzma
-rw-r--r-- 1 root root 9817 Feb 2 00:03 lzma.h
drwxr-xr-x 2 root root 4096 Feb 2 00:09 unicode
-rw-r--r-- 1 root root 11500 Nov 4 17:54 zbuff.h
-rw-rw-r-- 1 root root 16298 Jan 15 2017 zconf.h
-rw-r--r-- 1 root root 17203 Nov 4 17:54 zdict.h

-rw-r--r-- 1 root root 119972 Nov 4 17:54 zstd.h
-rw-r--r-- 1 root root 3751 Nov 4 17:54 zstd_errors.h
I also created a site-config.jam file thanks to which b2 finds libz, bz2, xz and zstd.
$ more /etc/site-config.jam
using gcc : : x86_64-w64-mingw32-g++ :
<cxxflags>-DBOOST_ASIO_HAS_STD_STRING_VIEW
<cxxflags>-DBOOST_ASIO_HAS_STD_IOSTREAM_MOVE
<cxxflags>--sysroot=/mingw
<cxxflags>-std=c++17 ;
using zlib : : <include>/mingw/include <search>/mingw/lib ;
using bzip2 : : <include>/mingw/include <search>/mingw/lib ;
using lzma : : <include>/mingw/include <search>/mingw/lib ;
using zstd : : <include>/mingw/include <search>/mingw/lib ;
Unfortunately this is not possible for ICU. Using -sICU_PATH did not work either.
My current command line to build is:
$ cd /mnt/boost_1_72_0
$ ./b2 toolset=gcc variant=release threading=multi link=static \
target-os=windows architecture=x86 address-model=64 abi=ms binary-format=pe \
-sICU_PATH=/mingw/lib \
--layout=system --prefix=/install \
--without-python --without-graph_parallel --without-mpi \
-j $(nproc) install
This prints:

You can run and reproduce this by my test Docker image:
$ docker run -it --rm bebuch/boost-with-static-icu-prepared:latest
What do I have to change to make icu switch to yes in the b2 run?
Edit 2020-02-03: Part of the answer is a bug that was fixed in Boost 1.73.0:
