; All-in-one Installer for all subprojects / software components of the

;
; PREREQUISITES:
;
; -> You must install the file cpudesc\cpudesc.dll into the working
;    directory before being able to compile this installer!
;
; -> The compiled binaries must be placed into the respective directories
;    under bin\ (you have to read this file in order to get those exact
;    locations and expected file names).

; NSIS plug-in for getting CPU information
!addplugindir cpudesc
