[CMake] Duplicated messages and check for g++

[Slava Semushin]

    Hello!

    When I run cmake I see following messages:

    tetaneg% cmake .
    -- Check for working C compiler: gcc
    -- Check for working C compiler: gcc -- works
    -- Check size of void*
    -- Check size of void* - done
    -- Check for working CXX compiler: c++
    -- Check for working CXX compiler: c++ -- works
    [skip]

    I have 2 questions:

    - Why for each check was printed 2 similar messages?
    - Why cmake always check compiler for C++? I dont need in this
      test, my program uses only gcc.

    May be I can tune it?

    Thanks in advance!
