Tests failing to run on MacOS (Darwin) due to shared library shenanigans, causing build to fail

[joelpmichael]

Following the MacOS instructions in the install guide at https://www.ngscopeclient.org/manual/GettingStarted.html (section 3.3.2), everything works until the end of the build.

Disabling tests using the cmake option -DBUILD_TESTING:BOOL=OFF allows the build to complete:

@lainy is this a known issue? Not tagging this as a v0.1 release blocker since it only affects the tests and FFTS is planned to be fully deprecated by v0.2
