Allow projected_kernel.c to compile when GSL is not available (!1514) · Merge requests · SWIFT / SWIFTsim

John Helly requested to merge lightcone_no_gsl_fix into master Mar 30, 2022

Compilation without GSL failed because projected_kernel_integrand() was defined but never used. This adds an #ifdef to remove the function if GSL is not available. I've also added a check in configure to catch the case where we have lightcones but no GSL.

This is an alternative to !1512 (closed). Fixes #794 (closed).
