Title: CMake Configuration for libiconv
Summary
This CMake script configures the libiconv project. It sets compile options, includes directories, configures header files (config.h, localcharset.h, iconv.h) by replacing specific macros, defines variables (BROKEN_WCHAR_H, HAVE_VISIBILITY, HAVE_WCHAR_T, ICONV_CONST, USE_MBSTATE_T), creates libraries (libcharset, libiconv) and an executable (iconv), and links them appropriately. It also defines header templates and removes specific files from the list.
