Re: [Quantlib-users] Using Quantlib with CMakeLists

[Jonathan S. <sw...@gm...>]

Hi Peter,

In your project’s CMakeLists.txt file you can use
target_include_directories[1] to tell cmake where to find the headers, and
target_link_directories[2] to tell cmake where to find the libraries for
linking.

Having said that, you should probably think about using a package manager
such as vcpkg to handle this kind of setup for you automatically.

Lastly, you mentioned that you created a .lib file but you seem to be using
make on Linux, which means you need to link against libQuantLib.a instead.
