Fix test cases whose behavior differs when their source or build tree is
under CMAKE_INSTALL_PREFIX by setting an install prefix under the build
tree. Otherwise they may fail when run under the default install prefix
(e.g. /usr/local).
Set the minimum required version of CMake high enough to avoid the
warning for CMAKE_LEGACY_CYGWIN_WIN32. The warning appears on stderr
and breaks the expected output matching.
Diagnostics which check the sanity of exported include paths
previously skipped over any path containing a generator expression.
Introduce a policy to issue an error message in such cases.
The export files created in the OLD behavior are not usable, because
they contain relative paths or paths to the source or build location
which are not suitable for use on installation. CMake will report an
error on import.
