Why not leave the build directory alone & let the cmake 1.1 PG handle it? Most
CMake-based ports can handle out-of-source building these days, and that's the
default for the cmake 1.1 PG, and the default setting here should work for the
vast majority of cmake-based ports.
To your query: You shouldn't try to write to or generate files outside the
${worksrcdir} (or ${worksrcpath}); all configuring, building, installing,
patching, etc must be done within the port's build path.
Hope this is useful! - MLD
