[CMake] EXECUTE_PROCESS problem

[Richard Wackerbarth]

I'm not sure, but I think that, in the UNIX case, your executable is  
not "sha1", but rather it is looking for the filename "sha1 -r".
Try

IF(UNIX)
   SET(CHKSUM_EXECUTABLE "/sbin/sha1")
   SET(CHKSUM_PARAMETERS  "-r")
ELSE(UNIX)
   SET(CHKSUM_EXECUTABLE "/usr/bin/sha1sum")
   SET(CHKSUM_PARAMETERS  ""
ENDIF(UNIX)

EXECUTE_PROCESS( COMMAND ${CHKSUM_EXECUTABLE} ${CHKSUM_PARAMETERS}  
$ENV{PP_ROOTDIR}/bin/PSWd OUTPUT_FILE
CHECKSUM.txt )

Although it won't affect the interpretation, note that this is not  
the appropriate syntax for
> #!/bin/sh

Perhaps that line should be something else.
