[Qt-creator] Shadow build problems

[Stephen Chu]

I tried the shadow build feature and find some problems with it:

1. If the project folder name has space in it, enabling shadow build 
will cause moc to fail. It complains that there are too many input files.

2. On Windows, rcc.exe reports that the qrc file does not exist. I think 
it's given a relative path from the build folder but the working dir is 
the project dir. Placing the shadow dir next to the project one solves 
it.

A couple of hoops to jump thru but it working now. Just FYI.
