Use Autotools to replace manual writing makefile

makefile_template.am

Bin_programs = XXX
Xxx_sources = YYY

autogen.sh

"{
    s/xxx/$1/
    s/yyy/$2/
    } " makefile_template.am > makefile.am

AutoScan
Autoheader
"/ac_init/a\
    am_init_automake " configure.scan > Configure.ac

Aclocal

Automake--add-missing--copy
Autoconf
./configure
Make

"S/yyy/$2 is not supported for multiple. cpp files and needs to be further optimized"

Call autogen.sh

Bash autogen.sh Test test.cpp

./test

And the result is the same as above.
