Q:

Setting up ccache with Qt Creator on Windows

I'm trying to set up ccache in Qt Creator on Windows.
Unfortunatelly I couldn't find any good instruction. How to make it working?
I have ccache installed with Cygwin. 
edit:
I've tried adding 
QMAKE_CXX+="ccache g++"

as additional parameter in qmake build step.
But in compile output I still have "g++ -c -g -Wall ..." and I suppose it should be "ccache g++ ..."

A:

It should be:
"QMAKE_CXX=ccache g++"

And you might need to rerun qmake from the Build menu if QtCreator doesn't update automatically the makefile after you add that parameter.
