InstallRequiredSystemLibraries currently defaults to installing to
bin on WIN32 and lib otherwise. This patch allows you to configure
this by using the variable CMAKE_INSTALL_SYSTEM_RUNTIME_DESTINATION.
It also switches the logic to use a single INSTALL(PROGRAMS) command
rather than two deprecated uses of the INSTALL_PROGRAMS command.
In InstallRequiredSystemLibraries the documentation details the
variable CMAKE_SKIP_INSTALL_RULES to skip installation. This
actually doesn't do anything, the variable required is named
CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS_SKIP. This commit amends the
documentation to point to the correct variable.
This adds copyright/license notification blocks CMake's non-find
modules. Most of the modules had no notices at all. Some had notices
referring to the BSD license already. This commit normalizes existing
notices and adds missing notices.
