Using two different math libraries in the same project confuses Visual C++ - c++

Question

My project needs to use both Micorsoft Visual C++ math.h and Intel MKL math.h.
Building with verbose details, I get:
1> Note: including file: C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include\cmath
1> Note: including file: E:\3rdParty\MKL\2017.1.143\windows\compiler\include\math.h
1> Note: including file: C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include\../../vc/include/math.h
1> Note: including file: C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include\crtdefs.h
1> E:\3rdParty\MKL\2017.1.143\windows\compiler\include\math.h(1577): warning C4005: 'HUGE_VALF' : macro redefinition
1> C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include\../../vc/include/math.h(104) : see previous definition of 'HUGE_VALF'
1> E:\3rdParty\MKL\2017.1.143\windows\compiler\include\math.h(1579): warning C4005: 'HUGE_VALL' : macro redefinition
1> C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include\../../vc/include/math.h(105) : see previous definition of 'HUGE_VALL'
1> E:\3rdParty\MKL\2017.1.143\windows\compiler\include\math.h(1581): warning C4005: 'HUGE_VAL' : macro redefinition
1> C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include\../../vc/include/math.h(96) : see previous definition of 'HUGE_VAL'
The "'HUGE_VALF' : macro redefinition" message is the one that made me be suspicious.
At first I just disabled that warning, but considering that this option would only mask a potential problem, I am looking for an alternative solution.
From lines 1 and 2, you can see that Visual Studio's cmath does not include Visual Studio's math.h, as it should, but MKL's file with the same name.
How can I set my CMakeLists.txt file so that the compiler can pick the right include files?

Answer 1

Just wrap one library.
For example, create header file:
#pragma once
namespace imath {
double sin(double a);
}
And in cpp
#include "Wrapper.h"
#include <intel/math.h>
namespace imath {
double sin(double a) {
return ::sin(a);
}
}
Do this for every symbol you need to use in common source.
And do not include C version of math.h you are using C++ so #include <cmath>.
