System requirements: A valid Bloomberg installation. The API headers and
dynamic library are downloaded from
<https://github.com/Rblp/blp> during the build step. See
<https://bloomberg.github.io/blpapi-docs/cpp/3.8> as well as
<https://www.bloomberg.com/professional/support/api-library/>
for API documentation. A recent-enough compiler with C++11
support is required.
