Summary:                    SelectLibraryConfigurations wrongly set
basename_LIBRARY
Description: 
When calling select_library_configurations( basename ) when basename_LIBRARY is
already in cache, the macro appends basename_LIBRARY to itself. The cache
variable is not modified, but subsequent uses of basename_LIBRARY can be
problematic.

Steps to Reproduce: 
1. Create a CMakeLists.txt that uses select_library_configurations and uses the
lib_LIBRARY variable afterwards, like this one (also attached):

[code]cmake_minimum_required(VERSION 2.8)

include( SelectLibraryConfigurations )

set( FOO_LIBRARY_RELEASE foo )
set( FOO_LIBRARY_DEBUG foo_d )
set( CMAKE_BUILD_TYPE Release )

select_library_configurations( FOO )

message( STATUS "FOO_LIBRARY = ${FOO_LIBRARY}" )[/code]

2. Run cmake twice.

[code]> cmake .
[...]
-- FOO_LIBRARY = optimized;foo;debug;foo_d
[...]
> cmake .
[...]
-- FOO_LIBRARY = optimized;foo;debug;foo_d;optimized;foo;debug;foo_d
[...][/code]

Additional Information: 
The issue can be resolved by using a temporary variable for building the list
instead of manipulating basename_LIBRARY directly.
