 [^1]: CMake 3.0 also removed several long deprecated features from very old versions of CMake and make one very tiny backwards incompatible change to syntax related to square brackets, so this is not entirely fair; there might be some very, very old CMake files that would stop working with 3. I've never seen one, though.

 [^2]: You will sometimes see `FATAL_ERROR` here, that was needed to support nice failures when running this in CMake <2.6, which should not be a problem anymore.
 
 [^3]: The `::` syntax was originally intended for `INTERFACE IMPORTED` libraries, which were explicitly supposed to be libraries defined outside the current project. But, because of this, most of the `target_*` commands don't work on `IMPORTED` libraries, making them hard to set up yourself. So don't use the `IMPORTED` keyword for now, and use an `ALIAS` target instead; it will be fine until you start exporting targets. This limitation was fixed in CMake 3.11.

 A useful tool in writing CMake builds that work cross-platform is `cmake -E <mode>` (seen in CMake files as `${CMAKE_COMMAND} -E`). This mode allows CMake to do a variety of things without calling system tools explicitly, like `copy`, `make_directory`, and `remove`. It is mostly used for the build time commands. Note that the very useful `create_symlink` mode used to be Unix only, but was added for Windows in CMake 3.13. [See the docs](https://cmake.org/cmake/help/latest/manual/cmake.1.html#command-line-tool-mode).

 For single-configuration generators, you can build your code with `-DCMAKE_BUILD_TYPE=Debug` to get debugging flags. In multi-configuration generators, like many IDEs, you can pick the configuration in the IDE. There are distinct flags for this mode (variables ending in `_DEBUG` as opposed to `_RELEASE`), as well as a generator expression value `CONFIG:Debug` or `CONFIG:Release`.
 
 Once you make a debug build, you can run a debugger, such as gdb or lldb on it.

 Now, if you `find_package(MyLib)`, CMake can find the build folder. Look at the generated `MyLibTargets.cmake` file to help you understand exactly what is created; it's just a normal CMake file, with the exported targets.
 
 Note that there's a downside: if you have imported dependencies, they will need to be imported before you `find_package`. That will be fixed in the next method.

 ## Debugging your CMake files
 
 We've already mentioned verbose output for the build, but you can also see verbose CMake configure output too. The `--trace` option will print every line of CMake that is run. Since this is very verbose, CMake 3.7 added `--trace-source="filename"`, which will print out every executed line of just the file you are interested in when it runs. If you select the name of the file you are interested in debugging (usually by selecting the parent directory when debugging a CMakeLists.txt, since all of those have the same name), you can just see the lines that run in that file. Very useful!
