How could I get vcpkg's cryptopp built with asan make target (address sanitizer)

[rturrado]

I have a CMake project that uses vcpkg as a submodule to install some dependencies, cryptopp between them.

Now, in order to build this project with ASAN (address sanitizer, in debug mode), it seems I need to compile all dependencies with ASAN; otherwise I get a link error such as error LNK2038: mismatch detected for 'annotate_vector': value '0' doesn't match value '1' in (this seems to be the case for Visual Studio 2022 17.2 and beyond; check here and here).

I've tried defining adding the -fsanitize=address to CMAKE_CPP_FLAGS or CRYPTOPP_COMPILE_OPTIONS before the first project() in any CMakeLists.txt file, thinking that way those vars would be passed to vcpkg before building cryptopp; but that's not working.

What are my options to get, under certain build configurations, a vcpkg's cryptopp build with ASAN?

Use overlay triplet and set VCPKG_CXX_FLAGS in it.

Many thanks for the quick answer @Osyotr.
