As a code library maintainer, if you want your users to be able to use find_package(MyPackage) in CMake files, you need to now how to create a CMake package.
Annoyingly, this is not a simple task!
If the user performs a local install, they may call cmake as:
build$ cmake -DCMAKE_INSTALL_PREFIX=../install ..
Referencing Your Package From Downstream Build
Once you have created your package, you will be wanting to be able to use find_package() in a downstream package.
The CMake variable CMAKE_PREFIX_PATH can be used to specify local install locations for your dependent packages.
A great resource on creating a CMake package can be found at https://cmake.org/cmake/help/git-master/manual/cmake-packages.7.html#creating-packages.
An working GitHub example repo which uses the CMake packaging system can be found at https://github.com/forexample/package-example.
