I would like to build qwt out of source so that I can have 1 source and build it for 32 bit and 64 bit for Visual Studio 2005 and Visual Studio 2008 similar to what I do will all of my cmake based libraries so that I can easily integrate qwt into my build process and folder structure. Is there an easy way to get out of source builds with QMake? I have looked at the qmake documentation and I have done some google searching but I can't find what I want.
Just run qmake in the build directory like you do with cmake
Thanks. I will have to experiment with that. The reason is I am using windows and visual studio. On the first project I tested (qwt) I got a path too long error. Darn windows not supporting long paths..

Did you have proper environment / PATH set ?
Try opening the visual studio command prompt and then trying compiling..
This was from a proper Visual Studio 2008 32 bit command prompt.
Okay. I tested and it appears to work if I shorten the path by substituting the long path with a drive letter.
subst k: x:\QMakeBased\Libraries\qwt-5.2.1
then
x:\32Bit\VC.90\Temp\Qwt-5.2.1>qmake -r k:\qwt.pro
then build and install..
Maybe I should bug microsoft for the reason why in 2010 we have a maximum command line length of 8K (or 8000?) in windows 7 64 bit.
But I guess that is a tremendous improvement over the past:
