qmake conditionals/arguments

Is it possible to create a .pro file that exposes configuration options.

Example:

Code:

---

qmake --enable-my-super-fantastic-features

---

I know I can set variables. So if the above is not possible, I can follow that path.

EDIT: Ehm, forget about that, you havn't asked how to deal with variables!

I never have seen such custom configuration options. At least I can't remember. But for Variables you can write

Code:

---

qmake "DEFINES += MYFEATURE"

---

then you can check it in your pro file with

Code:

---

contains( DEFINES, MYFEATURE ) {}

---

and you can use it right in your files

Code:

---

#ifdef MYFEATURE
  /*...*/
#endif

---

Yes, I think I'll follow that route.
Thanks.
