I faced this issue when building my project as MacOSX application, but it is also possible to occur on iOS application if you are using cmake. |

description
Compile errors occurred when Xcode project is generated from cmake on MacOSX big sur.
clang: error: no such file or directory: '/usr/lib/libiconv.dylib'Bacause iconv path is resolved by find_library in CocosConfigDepend.cmake as below.
find_library(ICONV_LIBRARY iconv)But ICONV_LIBRARY always be set
/usr/lib/libconv.dylibignoring sys_root. /usr/lib seems to be no longer available and it is located at/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.0.sdk/usr/lib/libiconv.tbdon big sur.I guess ICONV_LIBRARY is already defined by cmake system so find_library do nothing.

solution
I used other name so that avoid conflicting name.
