Sorry for hijacking this thread, but I'm wondering about this for some time, too. (And the information in the doc/wiki is somewhat dated and/or ambiguous [1,2,3,4]). I will just go on and write my thoughts and what I (think I) know, in the hope that somebody corrects those things I got wrong.
So summarizing the previous mesage in the thread, one can say: + cmake aware packages should provide LibraryConfig.cmake scripts (and optionally LibraryVersion.cmake scrips), just like they would provide pkg-config files. + developers should create FindLibrary.cmake scripts for packages they are using that are not cmake aware. I think that information should be transported more clearly, because in practice most cmake based software provides a FindLibrary.cmake file for itself. Also, I could not find a definitive answer on where these packages should put the LibraryConfig.cmake script. If I read the search paths in [1] correctly, the preferred paths are: + <prefix>/ on windows + <prefix>/(share|lib)/cmake/<name>*/ on linux, and + <prefix>/<name>.framework/Resources/ on Apple We have have every library and library-version in its own prefix and use shell modules[5] to provide the correct environment that a user wants. Is there any way to let cmake know about specific prefix directories it should be aware of? Unfortunately, the CMAKE_MODULE_PATH variable has to be manually set, and not influenced by the environment. Something like the PKG_CONFIG_PATH environment variable for pkg-config would be really nice to have in cmake. Another somehow related topic seems to be import/export of targets. Should a LibraryConfig.cmake or FindLibrary.cmake file create imported targets for the library? And is there any documentation on how to create a LibraryConfig.cmake file with support for components?
