Variable Source Path

I'm trying to get my NSIS script able to be compiled on two different machines with different directory structures. I thought I could simply:

Var Path
Function .OnInit
    StrCpy $Path "c:\test.txt"
FunctionEnd
Section
    File "${Path}"
SectionEnd

...but obviously variables are for run-time use only. What I need is some sort of compile-time constant. I was hoping to be able to create an NSH file on my machine that sets the source path to "c:\source_files", and the build machine could have the same NSH file, but point it do d:\project\latest". Or maybe even something simpler?

Any ideas?

TIA!

mypath.nsh:
!define thepath "c:\foo\bar"

install.nsi:
!include "mypath.nsh"
...
File "${thepath}\somefile.exe"

No real need to use an nsh for that, of course. Just put the define at the top of the script.

Thanks Anders!

@MSG, putting the !define at the top of the script won't allow that same script to run on multiple environments.

You can use relative paths in the define, or directly in the FILE commands. I do this to work at home and at the office, where my NSIS folders are on different drives

!define Addons "\NSIS Installers\Addons"

!AddPluginDir "${Addons}\Plugins"

!AddIncludeDir "${Addons}\Include"

...

!define SRCDIR ".\Ipls.3177"

File "${SRCDIR}\ArchHelpUtil*.ocx"
