I do set CPACK_NSIS_EXTRA_INSTALL_COMMANDS with embedded
newlines which works:

SET(CPACK_NSIS_EXTRA_INSTALL_COMMANDS "
		    ExecWait
\\\"$INSTDIR\\\\external\\\\oncrpc\\\\bin\\\\inst_pm.exe remove\\\"
		    CopyFiles
\\\"$INSTDIR\\\\external\\\\oncrpc\\\\bin\\\\oncrpc.dll\\\"
\\\"$SYSDIR\\\"
		    CopyFiles
\\\"$INSTDIR\\\\external\\\\oncrpc\\\\bin\\\\portmap.exe\\\"
\\\"$SYSDIR\\\"
		    CreateDirectory \\\"$SYSDIR\\\\drivers\\\\etc\\\"
		    CopyFiles \\\"$INSTDIR\\\\external\\\\oncrpc\\\\etc\\\\rpc\\\"
\\\"$SYSDIR\\\\drivers\\\\etc\\\"
		    ExecWait
\\\"$INSTDIR\\\\external\\\\oncrpc\\\\bin\\\\inst_pm.exe
$SYSDIR\\\\portmap.exe\\\"

look at:
http://cvs.savannah.nongnu.org/viewvc/tsp/CMakeLists.txt?root=tsp&view=markup

for properly indented CMakeLists.txt example.

I do encounter a "limit in size problem" with
CPACK_NSIS_EXTRA_INSTALL_COMMANDS
if I try to set it with a string which is longer than X character
the var content is truncated to X.

I'm not sure but I think X is about 255.
