I've built Qt 5.4 from source using MSVC 2008 since binaries for that are not available to download. I did an out-of-source build into a build directory ("msvc2008_32_build"), and an install into a third directory ("msvc2008_32"). Except for two compilation errors (now fixed), everything built and installed without a hitch.

Is it now safe to "make clean" in the build directory? (Or even to simply delete it entirely?) Is there anything in the build directory that is required to compile, link, or debug?

Paranoid, maybe, but it takes hours to build and install from source, and I don't want to have to do it again.

Thanks.
