I think Chandan meant "globally" for all executables.

That's the purpose of CMAKE_EXECUTABLE_SUFFIX
as already pointed  out by Michael.

see : cmake --help-variable "CMAKE_EXECUTABLE_SUFFIX"

Now it doesn't seems to work for Chandan.

I guess the variable is forcibly written by "CMakeGenericSystem.cmake"
during early CMake startup.
So that you cannot overwrite its value on the command line.
try to add "variable_watch(CMAKE_EXECUTABLE_SUFFIX)" at the very top
of main CMakeLists.txt

You may try to do that from within the CMakeLists.txt after the
"project(...)" statement (or enable_language)
