Remarks

  • The find_package way is compatible on all platform, whereas the pkg-config way is available only on Unix-like platforms, like Linux and OSX.

  • A full description of the find_package numerous parameters and options can be found in the manual.

  • Even though it is possible to specify many optional parameters such as the version of the package, not all Find modules properly uses all those parameters. If any undefined behaviour occur, it could be necessary to find the module in CMake's install path and fix or understand its behaviour.
