error: ‘strcmp’ was not declared in this scope

[gdamjan]

vulkan, glfw and glm installed from a package:

$ g++ -DNDEBUG -lvulkan -lglfw -std=c++11 hello_triangle.cpp 
hello_triangle.cpp: In member function ‘bool HelloTriangleApplication::checkValidationLayerSupport()’:
hello_triangle.cpp:823:64: error: ‘strcmp’ was not declared in this scope
                 if (strcmp(layerName, layerProperties.layerName) == 0) {
                                                                ^

adding #include <string.h> does compile it.

This is on ArchLinux, gcc-6.1.1, vulkan-headers-1.0.21, vulkan-intel 12.0.1 (mesa), glfw-x11 3.2-4, glm 0.9.7.5-1

Better use <cstring> because C++ though ;)
