c++ - 将jsoncpp外部库添加到我的qt项目中:(未找到架构x86_64的符号)

我正在尝试将jasoncpp库添加到我的C++ qt项目中。
我包括了标题，并链接了(我认为)库，但是出现了以下错误:
“找不到针对体系结构x86_64的符号”和“链接器命令失败，退出代码为1(使用-v查看调用)”。

找不到的符号显然是与jsoncpp库有关的符号。

这是我的makefile:

QT       += core gui webkitwidgets

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = JsonTest
TEMPLATE = app

SOURCES += main.cpp\
mainwindow.cpp

HEADERS  += mainwindow.h

FORMS    += mainwindow.ui

win32:CONFIG(release, debug|release): LIBS += -L$$PWD/../../../../../../../usr/local/Cellar/jsoncpp/0.5.0/lib/release/ -ljson
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/../../../../../../../usr/local/Cellar/jsoncpp/0.5.0/lib/debug/ -ljson
else:unix: LIBS += -L$$PWD/../../../../../../../usr/local/Cellar/jsoncpp/0.5.0/lib/ -ljson

INCLUDEPATH += $$PWD/../../../../../../../usr/local/Cellar/jsoncpp/0.5.0/include
DEPENDPATH += $$PWD/../../../../../../../usr/local/Cellar/jsoncpp/0.5.0/include

我真的不知道该如何进行，所以在此先感谢。

最佳答案

如果使用cmake安装它，请尝试以下命令:

mkdir -p build/debug
cd build/debug
cmake -DCMAKE_BUILD_TYPE=debug -DJSONCPP_LIB_BUILD_STATIC=ON -DJSONCPP_LIB_BUILD_SHARED=OFF -G "Unix Makefiles" ../..
make

更改

win32:CONFIG(release, debug|release): LIBS += -L$$PWD/../../../../../../../usr/local/Cellar/jsoncpp/0.5.0/lib/release/ -ljson
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/../../../../../../../usr/local/Cellar/jsoncpp/0.5.0/lib/debug/ -ljson
else:unix: LIBS += -L$$PWD/../../../../../../../usr/local/Cellar/jsoncpp/0.5.0/lib/ -ljson

INCLUDEPATH += $$PWD/../../../../../../../usr/local/Cellar/jsoncpp/0.5.0/include
DEPENDPATH += $$PWD/../../../../../../../usr/local/Cellar/jsoncpp/0.5.0/include

为了这:

unix|win32: LIBS += -ljsoncpp
