	# CMake provides no way to override the install prefix of a subdirectory,

	# as a separate project. However, as the example subdirectories use
	# install(... TYPE BIN) to install executables, it is possible to override
	# CMAKE_INSTALL_BINDIR temporarily to place them in any directory within
	# the install prefix. This is a hack, but it allows us to preserve the
	# examples' folder hierarchy in the installation directory (it is already
	# preserved by CMake in the build tree!) with minimal effort.
