C:\Users\Eric\Documents\GitHub\MuseScore\CMakeLists.txt:295: error: if given arguments: "STREQUAL" "x86" Unknown arguments speci

This line https://github.com/musescore/MuseScore/blob/master/CMakeLists.txt#L295 is giving the following error in Windows QtCreator (after I cleared all system environment variables accidentally!):

C:\Users\Eric\Documents\GitHub\MuseScore\CMakeLists.txt:295: error: if given arguments: "STREQUAL" "x86" Unknown arguments specified

I think it should be changed from:

IF($ENV{PROCESSOR_ARCHITECTURE} STREQUAL "x86")

into:

IF("$ENV{PROCESSOR_ARCHITECTURE}" STREQUAL "x86")

That is how all other IF statements look. Without knowing much about how CMAKE works, I suspect the reason is that if $ENV{PROCESSOR_ARCHITECTURE} evaluates to nothing, then that if statement become:

IF(STREQUAL "x86")

And so CMAKE mistakenly? thinks that STREQUAL is an argument to the if command.
