--------------------+-----------------------
 The file
 `${prefix}/libexec/llvm-5.0/lib/cmake/clang/ClangTargets-${cmake.build_type}.cmake`
 is installed with post-processing; it should get a reinplace:

 {{{
         file rename
 ${destroot}${sub_prefix}/bin/clang-${clang_executable_version}
 ${destroot}${sub_prefix}/bin/clang
 +        reinplace "s|/bin/clang-${clang_executable_version}|/bin/clang|g"
 \
             "${destroot}${sub_prefix}/lib/cmake/clang/ClangTargets-[string
 tolower ${cmake.build_type}].cmake"
 }}}

 (cmake.build_type is defined by the cmake-1.1 PG)
