libGRM.so does not link ICU (libicuuc), causes runtime error

[kojix2]

On Linux, libGRM.so requires ICU symbols but does not link to libicuuc.

Tested with:
https://download.opensuse.org/repositories/science:/gr-framework/xUbuntu_24.04/amd64/gr_0.73.14-1_amd64.deb

Reproduction

1. ICU is not listed by ldd:

   ldd /usr/gr/lib/libGRM.so
   # libicuuc.so is not shown

2. Loading with dlopen fails:

   #include <dlfcn.h>
   #include <stdio.h>
   int main() {
       dlopen("/usr/gr/lib/libGRM.so", RTLD_LAZY | RTLD_GLOBAL) ? puts("ok") : puts(dlerror());
   }

   Result:

   /usr/gr/lib/libGRM.so: undefined symbol: UCNV_FROM_U_CALLBACK_SUBSTITUTE_74
   

3. Workaround:

   LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libicuuc.so.74 ./test_grm_load
   # ok

Request

Please link libGRM.so with ICU (libicuuc) at build time.

This issue is fixed in commit 03b491b. However, we need a new release to fix the stable packages. In the meanwhile, you could switch to the unstable packages which are built from develop.
