cmake and ninja compiler complaining about GeneratePackage.cmake

[Chris2L]

Good day.

Compiling with Yocto using cmake and ninja. It complains about GeneratePackage.cmake line 59 https://github.com/wernerd/ZRTPCPP/blob/4abf86a35fd4845150b270a51b133860bfa8e313/cmake/Modules/GeneratePackage.cmake#L59

The round brackets () should be curly brackets {}. I patch it locally, but just a heads up. Not to schooled with git to submit a patch yet, sorry.

Kind regards Christo
