gph's Issues

make error

Hi,
I met some troubles when install the package.
In my computer(macOS), I have installed SoPlex. When I use make, such following errors:
GPH/src/core/Common.h:196:6: error: no template named 'optional' in namespace 'std'
std::optional<std::pair<std::vector, double>>
GPH/src/core/Common.cpp:184:6: error: no template named 'optional' in namespace 'std'
std::optional<std::pair<std::vector, double>>
PH/src/core/Common.cpp:229:11: error: no viable conversion from returned value of type 'pair<typename
__unwrap_ref_decay<vector<double, allocator > >::type, typename __unwrap_ref_decay<double &>::type>' (aka
'pair<std::__1::vector<double, std::__1::allocator >, double>') to function return type 'int'
return std::make_pair(std::move(localsolution), localobj);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3 errors generated.
make[2]: *** [CMakeFiles/gph.dir/src/core/Common.cpp.o] Error 1
make[1]: *** [CMakeFiles/gph.dir/all] Error 2
make: *** [all] Error 2

And I also use CLION to make, but has such error:
CMake Error at CMakeLists.txt:48 (message):
LP solver unknown

In fact, I can use SoPlex.
which soplex
/usr/local/bin/soplex

Could you help me ?
