[1137/1137] Linking CXX static library lib/libbenchmark_main.a
```
after this i have tried $sudo ninja install
then i have used this clang-19 to build sysbench benchmarking tool(i am trying to integrate wasm with sysbench)
when i am compiling i am getting error like
```

```
in clang/19/lib/ there is no wasm32-unknown-wasi-threads directory.
will it create or not after compilation of clang.
to generate that missed Dir what i need to do.
my main moto of this building clang-19 is
from WAMR community they suggested to install clan-19 to resolve the below import linking issues related to jump functions
example
```
admin1@admin1-VivoBook-ASUSLaptop-X515EA-P1511CEA:~/sysbench_main$ /home/admin1/Documents/wasm-micro-runtime/product-mini/platforms/linux/build/iwasm src/sysbench_with_setjmp_errors
[13:23:38:500 - 7A7431BB6740]: warning: failed to link import function (env, __wasm_longjmp)
[13:23:38:500 - 7A7431BB6740]: warning: failed to link import function (env, saveSetjmp)
[13:23:38:500 - 7A7431BB6740]: warning: failed to link import function (env, getTempRet0)
[13:23:38:500 - 7A7431BB6740]: warning: failed to link import function (env, testSetjmp)
Attempting to allocate 1064960 bytes of memory...
sysbench 1.1.0-2ca9e3f (using Lua Lua 5.3)
Exception: failed to call unlinked import function (env, saveSetjmp)
```
so conclusion is
if i install clang-19 properly i would able to solve those errors regarding jump functions .
You tell me am i in correct path to resolve this issues through clang-19
or do i have to rectify these errors in WAMR itself.
Thanks in advance.
