How to add depdency in waf builder's wscript script - c++

Question

In my project (which uses waf/wscript based build system), I am now adding mongodb c++ driver APIs. I figured out that 'libmongoclient.a' is not getting added as a linker option (at compile time) and I get all undefined reference to the mongodb c++ driver API calls.
I want to understand, how do I modify my wscript so that it picks up the mongoclient related library by itself and links it properly. It perhaps involves updating the configuration function of wscript. I am new to the waf build system, and not sure how to change it.
I have built and installed the mongodb c++ driver as follows:
- INCLUDE: /usr/local/include/mongo/
- LIB: /usr/local/lib/libmongoclient.a
I posted a similar question earlier in this regard, and the above one is more specific problem statement.

Since I am just invoking ./waf from within eclipse, I believe, the options that I specify into Eclipse's build environment are not being picked up by the waf (and hence the library option for mongoclient).

I figured this out and the steps are as follows:
Added following check in the configure command/function.
conf.check_cfg(package='libmongoclient', args=['--cflags', '--libs'],
uselib_store='MONGOCLIENT', mandatory=True)
After this step, we need to add a package configuration file (.pc) into /usr/local/lib/pkgconfig path. This is the file where we specify the paths to lib and headers. Pasting the content of this file below.
prefix=/usr/local
libdir=/usr/local/lib
includedir=/usr/local/include/mongo
Name: libmongoclient
Description: Mongodb C++ driver
Version: 0.2
Libs: -L${libdir} -lmongoclient
Cflags: -I${includedir}
Added the above library into the build function to the sepcific program which depends on the above dependency (i.e. MongoClient).
mobility = bld(
target='bin/mobility',
features='cxx cxxprogram',
source='src/main.cpp',
use='mob-objects MONGOCLIENT',
)
