安装mongo-cxx-driver-r3.4.0 cmake的时候报错:  

报错：

CMake Error at src/mongocxx/CMakeLists.txt:54 (find_package):By not providing "Findlibmongoc-1.0.cmake" in CMAKE_MODULE_PATH thisproject has asked CMake to find a package configuration file provided by"libmongoc-1.0", but CMake did not find one.Could not find a package configuration file provided by "libmongoc-1.0"(requested version 1.17.0) with any of the following names:libmongoc-1.0Config.cmakelibmongoc-1.0-config.cmakeAdd the installation prefix of "libmongoc-1.0" to CMAKE_PREFIX_PATH or set"libmongoc-1.0_DIR" to a directory containing one of the above files.  If"libmongoc-1.0" provides a separate development package or SDK, be sure ithas been installed.

原因：  mondo-c-drive没有安装或者没有正确安装 

报错：

因为之前安装过 所有/usr/local/include/libmongoc-1.0 这个库存在  备份或者删除 重新安装

cd /usr/local/include/libbson-1.0/ mv libmongoc-1.0 libmongoc-1.0.baklibmongoc 清除之后重新安装 cd cmake-build make clean make 
make install
