为什么真正的匹配器不起作用？

Question

我试图使用Truly匹配器，以捕获变量。

#include "gmock/gmock.h"
#include "gtest/gtest.h"

void TestsClass::Set_Values(double TmpStmp, double Point_0_Y, 
double Point_0_Width, double Point_0_Qual, bool RCom_Flag)
{
struct pData;

pData.var1 = TmpStmp;
pData.Point_0.Point_0_Y = Point_0_Y;
pData.Point_0.Point_0_Width = Point_0_Width;
pData.Point_0.Point_0_Qual = Point_0_Qual; 

EXPECT_CALL(mockFunction, Function(_)).WillOnce(DoAll(SetArgPointee<0>(pData), Return(RCom_Flag)));


EXPECT_CALL(
        mockArHudModuleWrapper,
        updatePackage(Matcher<const ArHud::MergedEgoLaneCenterLine&>(
            Truly([p0Y = Point_0_Y] (const ArHud::MergedEgoLaneCenterLine package) -> bool {
             package.getPoint(0) == p0Y; 
             return true;
            })
            ))); 

}

如您所见，我正在尝试捕获p0Y。

但是，当我尝试构建它时，出现错误：

line 1813: error #20: identifier "p0Y" is undefined
  EXPECT_CALL(
line 1813: error #17: expected a "]"

我省略了模拟类定义和语法的其他部分，因为我认为它们与这种情况无关。
