"program. This is because cmake will then be able to escape spaces "
"in the executable path. An optional argument OUTPUT_VARIABLE "
"specifies a variable in which to store the output. "
"To capture the return value of the execution, provide a RETURN_VALUE. "
"If OUTPUT_VARIABLE is specified, then no output will go to the "
"stdout/stderr of the console running cmake.\n"

"EXEC_PROGRAM, but the old command has been kept for compatibility."
