[CMake] How to invoke 64 bit cmd.exe from cmake script onWindows 7 (x64).

[Alexander Tarnopolsky]

Thanks for prompt reply.

In a simple case I invoke just interactive shell using full path to
64bit cmd.exe :

file (TO_NATIVE_PATH "$ENV{COMSPEC}" SHELL)
SET (ARGS /k)
execute_process (COMMAND ${SHELL} ${ARGS})

Still I see that the cmd process running as 32bit (in TaskManager).

Where is ${SHELL} defined? What is its value?

I suspect you could use find_program() with appropriate arguments to
specify that you want the 64-bit cmd.exe.
