Issue with cstring standard header

Dear all,

I have installed the C++ compiler with Parallels XE 2017 on a fresh Ubuntu 16.04 LTS distribution.

I am trying to compile a first test program, configured with CMake and the Unix Generator(icc).

Compilation fails on #include<cstring>, with a lot of messages like this:

    /usr/include/c++/5/cstring:75: error: the global scope has no "memchr"
    using ::memchr;

1. Is this normal that standard gcc headers are used? It seems no cstring header is shipped with icc.
2. How can I fix this? Other stdlib c headers seem to work.

Thanks!
