Using OSX environement variables in a .pro file [SOLVED]

[kloveridge]

I have Qt on my laptop and desktop. I have a library I had to move from one drive to another on my desktop. Now, my .pro file can't find the library unless I manually change the library path between my Desktop and laptop.

Currently my .pro file is like this:

@DEFINES += OSMac_
MAYALOCATION=/Applications/Autodesk/maya2015
INCLUDEPATH += $$MAYALOCATION/devkit/include@

What I would rather have is to have MAYALOCATION be defined by an environment variable on my system. I just don't know how to access environment variables in the .pro file

This is a basic problem I'm sure. But it doesn't change the fact I can't do what I need to do until I figure it out!

This worked. I made a environment variables called MAYAROOT with the appropriate path for the laptop and desktop. I changed the code above to this and everything worked:

@DEFINES += OSMac_
INCLUDEPATH += $$MAYAROOT/devkit/include@
