# Control where libraries and executables are placed during the build.
# With the following settings executables are placed in <the top level of the
# build tree>/bin and libraries/archives in <top level of the build tree>/lib.
# This is particularly useful to run ctests on libraries built on Windows
# machines: tests, which are executables, are placed in the same folders of
# dlls, which are treated as executables as well, so that they can properly
# find the libraries to run. This is a because of missing RPATH on Windows.
