The location with -L is not sufficient in ICU_LIBS.
The list of libraries to link with should be put as well.
For instance:
ICU_LIBS="-L/usr/lib/icu -licui18n -licuuc -licudata"
When using the version of ICU that ships with the distribution (libicu-dev
package on Ubuntu), adding only "--with-icu" should be enough.
The locations of includes and libraries will be automatically found.
I'm not sure that's your case though. On one hand, /usr/include/unicode is
where the package puts the ICU includes, but on the other hand
it doesn't create any /usr/lib/icu directory.
And Ubuntu 22.04 LTS brings ICU 70, not ICU 71.
If you need a self-built version of ICU, it might be simpler to use pkgconfig
as an alternative to ICU_CFLAGS/ICU_LIBS, for instance:
./configure --with-icu PKG_CONFIG_PATH=/path/to/icu/lib/pkgconfig
where /path/to/icu was passed as the prefix to ICU4C configure
invocation. It's recommended to install custom builds to specific
locations instead of overwriting the libraries that are part of
the distribution (otherwise it becomes unmaintainable)
