如何在我的Qt项目中包含muparser库？

git clone https://github.com/beltoforion/muparser.git

INCLUDEPATH += /path/to/muparser/include
LIBS += -L/path/to/muparser/lib -lmuparser

include_directories(/path/to/muparser/include)
link_directories(/path/to/muparser/lib)

target_link_libraries(your_target_name muparser)

#include "muParser.h"

double calculate(double x) {
    mu::Parser parser;
    parser.DefineVar("x", &x);
    parser.SetExpr("sin(x) + cos(x)");
    return parser.Eval();
}
