The macro looks fine (assuming you actually call it somewhere). And I also assume that the line that fails is the find_package(GSL REQUIRED)
I suspect that it fails because you installed GSL in a local directory that is not in a location known to cmake (E.g not in /usr/local/lib or something similar) Can you specify the path you installed GSL to? In order for CMake to find package in a non-standard location, you can set the GSL_ROOT <https://cmake.org/cmake/help/latest/variable/PackageName_ROOT.html#packagename-root> cmake variable before calling find_package(GSL). You should set it to wherever you installed the GSL library locally.
