Comment (by kencu):

 Are you just trying to use cmake in your own project, outside of MacPorts?
 If so, I get this with your CMakeLists.txt:
 {{{
 $ which cmake
 /opt/local/bin/cmake

 $ cmake ../
 -- The C compiler identification is Clang 5.0.2
 -- The CXX compiler identification is Clang 5.0.2
 -- Check for working C compiler: /opt/local/bin/cc
 -- Check for working C compiler: /opt/local/bin/cc -- works
 -- Detecting C compiler ABI info
 -- Detecting C compiler ABI info - done
 -- Detecting C compile features
 -- Detecting C compile features - done
 -- Check for working CXX compiler: /opt/local/bin/clang++
 -- Check for working CXX compiler: /opt/local/bin/clang++ -- works

 -- Detecting CXX compile features
 -- Detecting CXX compile features - done
 ICONV_HEADER = /usr/include
 ICONV_LIB = /usr/lib/libiconv.dylib
 -- Configuring done
 -- Generating done
 }}}

 However, inside of a MacPorts' build (using cmake 1.1 PG), it looks fine:
 {{{

 -- The CXX compiler identification is Clang 5.0.2
 -- Check for working C compiler: /opt/local/bin/clang-mp-5.0

 -- Detecting CXX compile features
 -- Detecting CXX compile features - done
 ICONV_HEADER = /opt/local/include
 ICONV_LIB = /opt/local/lib/libiconv.dylib
 }}}
