Unable to compile the CppAD on universal windows platform

[GiulioRomualdi]

I'm trying to port CppAD on vckg. The compilation on universal windows platform fails with the following error

Make Error: TRY_RUN() invoked in cross-compiling mode, please set the following cache variables appropriately:

This message is during a check to see if C++11 is available; see
https://en.cppreference.com/w/cpp/language/types

If these tests fail, CPPAD_USE_CPLUSPLUS_2011 will be zero, see
https://coin-or.github.io/CppAD/doc/preprocessor.htm#Documented%20Here.CPPAD_USE_CPLUSPLUS_2011

which will be defined in include/cppad/configure.hpp after cmake is run.

As a post script here, I am considering requiring C++11 since the standard is over 10 years old.

[bradbell]

I have converted CppAD to require c++11; see the heading 12-03 on
https://coin-or.github.io/CppAD/doc/whats_new_20.htm

Please see what the state of this issue is with the current master.

Thanks a lot @bradbell ! To clarify a bit the context in which @GiulioRomualdi opened the issue, the problem arised when adding CppAD to vcpkg (https://docs.microsoft.com/en-us/cpp/build/vcpkg?view=msvc-160), and it was reported by vcpkg's CI system, and it may be tricky to try to replicate it. I general, if try_run is not used anymore, I think it is ok to close the issue, and once a new release of CppAD is ready we will update the vcpkg port and check if now it compiles fine on uwp in vcpkg's CI system.
