I've installed the latest version of the above package as shown below
but still meet the same error message:

$ dpkg -l libthai0 | grep ^ii
ii  libthai0:amd64 0.1.28-3     amd64        Thai language support library

Furthermore, I compiled and installed the latest git master version of
libthai. See following for more info.

$ git clone https://github.com/tlwg/libthai.git tlwg/libthai.git
$ sudo apt-get build-dep libthai
$ cd tlwg/libthai.git
$ ./autogen.sh
$ ./configure
$ make -j44
$ sudo make install

Then rebuild emacs from scratch but still will meet the same error as
shown below:

/usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/10/../../../x86_64-linux-gnu/libm17n-core.a(mtext-wseg.o):
undefined reference to symbol 'th_brk@@LIBTHAI_0.1'
/usr/bin/ld: /usr/local/lib/libthai.so.0: error adding symbols: DSO
missing from command line
collect2: error: ld returned 1 exit status
make[1]: *** [Makefile:655: temacs] Error 1
make[1]: Leaving directory '/home/werner/Public/editor/emacs/emacs.git/src'
make: *** [Makefile:424: src] Error 2
