Yes. There should be something in the wiki, and the make page for cmake, under find_package(). Here is also an exmaple how to do it for a library: https://projects.kde.org/projects/kde/kdeexamples/repository/revisions/master/show/buildsystem/HowToInstallALibrary > does this rely on > OpenEXR using cmake for their builds?

Personally, I don't consider it best practice.
