Catch 2.11.0 fails to build tests

[Psypher9]

When running make for the full solution, the Catch 2 dependency fails to build resulting in the following errors

.../tests/catch.hpp:10717:58: error: call to non-‘constexpr’ function ‘long int sysconf(int)’
10717 |     static constexpr std::size_t sigStackSize = 32768 >= MINSIGSTKSZ ? 32768 : MINSIGSTKSZ;

and

/tests/catch.hpp:10776:45: error: size of array ‘altStackMem’ is not an integral constant-expression
10776 |     char FatalConditionHandler::altStackMem[sigStackSize] = {};

These errors are directly addressed in an April 2021 release of Catch 2, found here. The original issue is here.

Expected Behavior:

• I can run a full build with make
  • The tests build
  • The tests run and pass
• Catch 2 is updated to the latest non-breaking version
