Re: [Quantlib-users] Quantlib in CLion

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

I took a quick look at your CMakeLists.txt file and fixed it up here:
https://gist.github.com/sweemer/dff4b0294eff698a3d670811549d3c35

For my gist to work you'll need to download the latest version 1.25 of
QuantLib. The gist may not work perfectly but it should be a good starting
point.

You will want to spend some time to review the CMake documentation[1] for
how to set the include and link properties for your project as there are
many more details that cannot be covered here.

As far as CLion is concerned, I'm not sure how to get it working, but based
on the blog link that you shared, the first step seems to be to tell CMake
to configure your build with the correct compiler[2].
