[Development] Qt4.8.x, qdoc3 not available Qt env variables from *.qdocconf file

[Denis Shienkov]

Hello, Qt developers.

Why not available Qt env variables from *.qdocconf file?

For example, 

I need specify path to Qt Doc installation directory from my.qdocconf file:

...
indexes = $QT_INSTALL_DOCS/doc/html/qt.index
...

After make: 

$qmake my.pro file 

creates a Makefile with docs target, then I do:

$make docs

But path QT_INSTALL_DOCS is not available, also  I'm try write  $$QT_INSTALL_DOCS,
bur result negative.

Help me please, how resolve this problem for Qt 4.8.x ?


Best regards,
Denis
