No, it's a separate thing. These configuration files are installed as part 
of issuing `b2 install` from a release. So you get the headers in 
/usr/local/include, the libraries in /usr/local/lib, and the configuration 
files in /usr/local/lib/cmake (assuming the default prefix of /usr/local/). 
This Boost installation is then used from CMake via find_package like f.ex.

https://github.com/boostorg/boost_install/blob/develop/.travis.yml#L59
https://github.com/boostorg/boost_install/blob/develop/test/filesystem/CMakeLists.txt

The CMakeLists.txt files, on the other hand, are used with a different 
workflow; you download/submodule the libraries from Github into 
subdirectories of your project, and then use them from CMake with 
add_subdirectory. Like f.ex.

https://github.com/boostorg/mp11/blob/develop/.travis.yml#L248
