求助 visual studio 2019，引用头文件出错，和命名空间出错

Question

#include <OpenMS/KERNEL/MSSpectrum.h>  //这里出错了，说是无法打开openms/kernel/msspectrum.h
#include<iostream>

using namespace OpenMS;  /这个地方也出错了，说是，名称必须是命名空间名
using namespace std;

int main()
{
    // Create spectrum
    MSSpectrum spectrum; //这个地方也出错，我怀疑还是头文件不对，或者命名空间
    Peak1D peak;         //这个地方也出错，我怀疑还是头文件不对
    for (float mz = 1500.0; mz >= 500; mz -= 100.0)
    {
        peak.setMZ(mz);
        spectrum.push_back(peak);
    }

    // Sort the peaks according to ascending mass-to-charge ratio
    spectrum.sortByPosition();

    // Iterate over spectrum of those peaks between 800 and 1000 Thomson
    for (auto it = spectrum.MZBegin(800.0); it != spectrum.MZEnd(1000.0); ++it)
    {
        cout << it->getMZ() << endl;
    }

    // Access a peak by index
    cout << spectrum[1].getMZ() << " " << spectrum[1].getIntensity() << endl;

    // ... and many more
    return 0;
}

新建的vs2019项目，复制学习教程上的一段代码，这个头文件包我有，这个头文件里还有别的头文件，都在Openms路径下）

Answer 1

#include 改为 #include "OpenMS/KERNEL/MSSpectrum.h" 试试
