Hello, After Craig's very interesting presentation at CppCon 2019* I learned a bunch of new things which I of course immediately wanted to try out**.
I read about the write_basic_package_version_file which is in CMakePackageConfigHelpers. Craig also mentioned in the presentation that you can have a so called API-version in the target's name. And that for example Qt does this (Qt5Core, which has the MAJOR number 5 in its target name). For my target name I prefer to have the API version after a dash, like how GLib and DBus packages do it: libglib-2.0.so.0.6200.1 on current Ubuntu, for example in /usr/lib/x86_64-linux-gnu. I wonder what that means for the <filename> property of write_basic_package_version_file. In the autotools and meson world, the usage of pkg-config files seems to indicate that the same filename naming scheme applies to the .pc file: /usr/lib/x86_64-linux-gnu/pkgconfig/glib-2.0.pc This allows me to distinguish between older MAJOR API versions of GLib and newer MAJOR API versions of it, using FindPkgConfig*** Supposedly something similar is possible with find_package's .cmake files as installed by write_basic_package_version_file? How do I provide a PackageNameConfigVersion.cmake for major version 1.0 and 2.0 (the equivalent of PackageName-1.0.pc and PackageName-2.0.pc in the pkgconfig directory)?
