Discussion: Can vcpkg use the compiler specified from the CMake command line arguments in manifest mode?

[xb284524239]

In my screenshot, I have selected the Clang 19.1.0 x86_64-pc-windows-msvc kit, but vcpkg always uses MSVC (cl.exe) to compile the third-party libraries. However, my own source code will be compiled with clang++.exe.

Although the entire compilation process completes without errors, and the program can run, I am still concerned about potential ABI compatibility issues between the third-party libraries and my own source code, because they are compiled with two different compilers.

BTW, I use LLVM (Clang) because tools like clangd, clang-tidy, clang-format, etc., are helpful for me.

No. You have to write a toolchain file and a custom triplet. See https://learn.microsoft.com/en-us/vcpkg/users/triplets#vcpkg_chainload_toolchain_file

No. You have to write a toolchain file and a custom triplet

or you generate a custom triplet with the settings of the calling cmake process. Requires writing a custom vcpkg toolchain however

It's a bit difficult for me. I think it requires a very good understanding and familiarity with CMake.
