Actually, in my opinion that was also a bug with other versions of
CMake.
Before this commit, in Installation/src, CGAL_CONFIGURED_LIBRARIES was
set to the empty string "" *in the parent scope* (Installation),
then the variable is modified in the current scope Installation/src, and
then the variable value is copied to a cache variable of the same name.
In my opinion, that means that the parent scope (Installation) has a
non-cache variable CGAL_CONFIGURED_LIBRARIES that is empty (""), and a
cache variable that is not empty (that contains, for example
"CGAL_Core;CGAL_Qt4;CGAL_ImageIO"). The document of CMake-3.0 precisely says
that the semantic of variables is such that cache variables have the
lowest priority. See:
http://www.cmake.org/cmake/help/v3.0/manual/cmake-language.7.html#variables
As far as I know, that was supposed to be the same for CMake 2.8, but I
cannot find out where it is described in the documentation. Anyway, the
bug was visible with CMake 2.8 and not with CMake 3.0.
The patch simply does not set the empty value of
CGAL_CONFIGURED_LIBRARIES in the parent scope, but only in the current
local scope.
