Looks like the CMake argument used to switch between static/shared objects has either changed or there is a typo in the documentation.
Noticed warnings when using the `BUILD_SHARED_LIBRARIES` variable in the
README about it not being used, and didn't find static '.a' libraries in Linux once built with it set to `off`. However, after examining the
CMakeLists.txt, it would appear the correct variable name is `BUILD_SHARED_LIBS`. I was able to build the static libraries when using the latter variable.
