I'm trying to include mongo-cxx-driver into my CMake project.

Here is part of my root CMakeLists.txt

project(testprj)
add_subdirectory(libbson)
add_subdirectory(mongo-c-driver)
add_subdirectory(mongo-cxx-driver)

While libbson, and mongo-c-driver compiles without problems, mongo-cxx-driver returns errors. It seams CMake cannot locate mongo-c-driver.

CMake Error at mongo-cxx-driver/src/mongocxx/CMakeLists.txt:23 (find_package):
By not providing "FindLibMongoC.cmake" in CMAKE_MODULE_PATH this project
has asked CMake to find a package configuration file provided by
"LibMongoC", but CMake did not find one.

Could not find a package configuration file provided by "LibMongoC"
(requested version 1.5.0) with any of the following names:

LibMongoCConfig.cmake
libmongoc-config.cmake

Add the installation prefix of "LibMongoC" to CMAKE_PREFIX_PATH or set
"LibMongoC_DIR" to a directory containing one of the above files. If
"LibMongoC" provides a separate development package or SDK, be sure it has
been installed.
