There's a small hiccup in building a Windows version of 1.5-rc5. When
you configure in the CMake GUI, you can ask for a Debug or Release
project before you hit Generate. If you ask for a Debug project, you
can still change it to Release in Visual Studio, and it will build
successfully. BUT: the Install project will fail, because it tries to
install libopen-pald.pdb (possibly others too, I didn't check). It's a
minor thing, only nuisance value. If you set a Release project in
CMake, everything works fine.
