★將第三方函示庫(函數庫/函式庫)引用(整合)到QT專案之中

Code:

#gsl.pri
#相關檔案來源:C:\Qt\Qt5.12.11\Tools\mingw730_64\msys\local
# 宏定义项，指明采用GSL
DEFINES += GSL_DLL

# 指明GSL库所对应的头文件所在目录
INCLUDEPATH += $$PWD/include

# 指明依赖库关系
LIBS += -L$$PWD/lib -lgsl
LIBS += -L$$PWD/lib -lgslcblas

#QT5_Use_GSL.pro

QT -= gui

include($$PWD/gsl/gsl.pri)

CONFIG += c++11 console
CONFIG -= app_bundle

# You can make your code fail to compile if it uses deprecated APIs.
# In order to do so, uncomment the following line.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0

SOURCES += \
        main.cpp

# Default rules for deployment.
qnx: target.path = /tmp/$${TARGET}/bin
else: unix:!android: target.path = /opt/$${TARGET}/bin
!isEmpty(target.path): INSTALLS += target

//main.cpp
#include <QCoreApplication>
#include <QDebug>
#include <gsl/gsl_sf_bessel.h>
#include <stdio.h>

void Pause()
{
    printf("Press Enter key to continue ...");
    fgetc(stdin);
}
int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
    double x = 5.0;
    double y = gsl_sf_bessel_J0 (x);
    printf ("J0(%g) = %.18e\n", x, y);
    //qDebug()<< "J0(%g) = %.18e\n", x, y;
    Pause();
    return 0;//return a.exec();
}
