[CMake] problem with shortcut CPACK/NSIS

[pellegrini]

Dear all,

I know that this issue has been raised several times but all the 
solution I tried failed up to now.

We have a Fortran 90 project for which we would like to create a NSIS 
installer using CPACK. When installing the software
we would like:

     - the PATH to be updated with the installation path
     - to set another environment variable called SXTALSOFTSUITE
     - create desktop and SMP shortcuts

All the trials we did up to now to create the SXTALSOFTSUITE failed even 
when using the command:

set(CPACK_NSIS_EXTRA_INSTALL_COMMANDS "WriteRegStr HKCU 'Environment' 
'SXTALSOFTSUITE' '$INSTDIR'")

All the trials we did to update the path failed even when using:
set(CPACK_NSIS_EXTRA_INSTALL_COMMANDS "Push 'PATH'
Push 'A'
Push 'HKCU'
Push '$INSTDIR\\\\bin'
Call EnvVarUpdate
Pop  '$0' ")

However, the installation process by itself worked as all the files are 
present in the installation directory. I have all the rights on my 
machine so it may be not a permission problem. This drives me crazy.

You will find enclosed my CPACK files. If one of you could find what is 
wrong with it it would be great.

thanks in advance
