mongo-c-driver cannot find libbson

Question

I'm trying to build the mongo-cxx-driver (eventually), and the first step is to build the mongo-c-driver (which requires libbson).

I'm running Windows 10 and using Visual Studio 2015 as my compiler. I was able to run CMake and build libbson just fine all of the projects built just fine. Now I have copies of bson-static-1.0.lib built in mongo-c-driver/src/libbson/build/Debug/ and mongo-c-driver/src/libbson/build/Release/. This seems like everything is correct.

The next step is to build the mongo-c-driver. I ran CMake and tried to create the Visual Studio solutions, but got the errors:

Could NOT find OpenSSL, try to set the path to OpenSSL root folder in the system variable OPENSSL_ROOT_DIR (missing:  OPENSSL_LIBRARIES OPENSSL_INCLUDE_DIR) 
Searching for sasl/sasl.h
  Not found (specify -DCMAKE_INCLUDE_PATH=C:/path/to/sasl/include for SASL support)
Searching for libsasl2
  Not found (specify -DCMAKE_LIBRARY_PATH=C:/path/to/sasl/lib for SASL support)
Current version (from VERSION_CURRENT file): 1.3.5
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
BSON (ADVANCED)
    linked by target "mongoc_shared" in directory C:/Users/sdf/Downloads/mongo-c-driver-1.3.5
    linked by target "mongoc_static" in directory C:/Users/sdf/Downloads/mongo-c-driver-1.3.5

Configuring incomplete, errors occurred!
See also "C:/Users/sdf/Downloads/mongo-c-driver-1.3.5/build/CMakeFiles/CMakeOutput.log".

It looks like the variable BSON isn't set to the right value -- it's value is BSON-NOTFOUND right now. Does anyone know what the correct value is for BSON, and if it should have gotten set automatically during the process of compiling libbson?

Please follow the "installing on Windows" instructions carefully:

https://api.mongodb.com/c/current/installing.html#building-windows

It seems you're missing the part where you set CMAKE_INSTALL_PREFIX when building libbson, then install libbson and build libmongoc with the same CMAKE_INSTALL_PREFIX setting.

First, you need build INSTALL project in libbson sln (run vs in admin mode, because it need create lib folders like linux way)

Then define BSON_INCLUDE_DIR to include folder which the INSTALL project created and BSON to lib file you build for example C:/Program Files/libbson/lib/bson-static-1.0.lib in cmake (This BSON naming is problematic, should rename to BSON_LIB)
