erros when building under linux

[chunleili]

two fatal errors occur when building in the manjaro!

building tools: cmake and make

/home/cl/codes/my/SPlisHSPlasH/extern/Catch2/catch.hpp:8223:45: error: size of array ‘altStackMem’ is not an integral constant-expression
8223 | char FatalConditionHandler::altStackMem[sigStackSize] = {};

/home/cl/codes/my/SPlisHSPlasH/extern/Catch2/catch.hpp:8164:58: error: call to non-‘constexpr’ function ‘long int sysconf(int)’
8164 | constexpr static std::size_t sigStackSize = 32768 >= MINSIGSTKSZ ? 32768 : MINSIGSTKSZ;
| ^~~~~~~~~~~

Hi, thanks for reporting this issue. It seems that this can be fixed by simply upgrading the version of Catch2. If you want a quick fix, just exchange the header extern/Catch2/catch.hpp with a more recent version and everything should work fine. We're working on pushing a fix soon.
