Not much, unfortunately. > I've read a discussion for this topic at [1] and [2]. > Also, at your blog, you wrote [3], that Harald Fernengel doing some work on > this.

Well, Clinton Stimpson is the maintainer of FindQt4.cmake in CMake, and I mostly merge the fixes there to the version in KDE. So actually he's the maintainer, but I'm also not the completely wrong person here :-) > Also, I'm interested to know, why FindQt4.cmake doesn't utilize pkg-config > for most introspection of Qt.

In first > case, qmake can be used for multiple cross-compilation environments. In general, CMake tries not to rely on any additional external tools, and pkg-config is one of those tools. I have (until now) never cross compiled anything with Qt. How does a typical Qt installation for cross compiling look like ? I guess it has native tools (qmake, moc, uic), etc. When FindQt4.cmake is executed, it queries qmake for information. Does this also work for a cross-compilation installation of Qt ? What are the results of a FindQt4.cmake with a cross-compiling qmake ? > Currently, I'm going to use simple FindQt4.cmake with some hardcoded paths, > that will override system wide one. > > Sorry for writing you directly instead of posting to a mailing list. > I just wasn't sure to which of cmake or kde-buildsystem mailing lists to > post. :) I'm all for moving this discussion to a public list. CC'ing the cmake -list.
