[CMake] Combined Static Libraries

[speedy]

Hello Daniel, Alan,

      you might be in luck if you are using VC++ generator, I had a
      need for a similar feature - patch is in the attachment.

      It simply adds the possibility to pass additional link flags /
      parameters to the linker upon static library build, defined
      overall or per build type (aka. VC++ configuration).

      I plan to do a bit more work on it when need arises, to remove
      cmake's global static library remapping to .exe at link time.
      For now, I'm meta-building only static libs with cmake.

      Usage:
      
ADD_LIBRARY(lib_name STATIC [files_here])

SET_TARGET_PROPERTIES(lib_name PROPERTIES
      LINK_FLAGS_DEBUG "[additional debug lib files/paths here +
      additional linker options if any]"
      LINK_FLAGS_RELEASE "[release lib files/paths here + additional
      linker options if any]")

      Cheers & hope it helps!
