我正在尝试在Ubuntu 16.04上测试mongodb c ++驱动程序。
驱动程序安装在${Devfolder}/sdk/mongodb/中
测试在${Devfolder}/testMongoDb/中。
使用以下代码对代码进行了编译和测试：
export PKG_CONFIG_PATH=${Devfolder}/sdk/mongodb/lib/pkgconfig
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:${Devfolder}/sdk/mongodb/lib
c++ --std=c++11 test.cpp -o test $(pkg-config --cflags --libs libmongocxx)
然后我想在我的CMake项目中使用mongodb驱动程序。
ugitho@ugitho:projects$ tree -L 3

但是我遇到了以下错误：
ugitho@ugitho:build$ cmake ..

编辑*：
这里是CMakeLists.txt和test.cpp。

您对我在这里错过的事情有任何想法吗？
更新：
使用新的CMakeLists.txt，不再出现cmake错误。

我设法使用此CMakeLists.txt进行编译。
新项目配置即将推出。 {GTest＆Boost＆MongoDb C ++驱动程序}
谢谢！
