vcpkg install files appearing in wrong directory

[joculatrix]

Hello!

I've followed through the Install and use packages with CMake guide. It worked as-is, but my LSP (clangd) didn't recognize that fmt/core.h existed in-editor which is, of course, not great for editing purposes. Based on a suggestion I saw online, I added the following line to my CMakeLists.txt:

SET(CMAKE_EXPORT_COMPILE_COMMANDS 1)

This did get clangd to stop throwing errors, however for some reason doing this caused vcpkg to place vcpkg_installed/ and vcpkg-manifest-install.log in the project root directory instead of under build/ where those were generated before. Aside from the above line added to my CMakeLists and my generator being set to Unix Makefiles instead of Ninja (I'm on Linux), my project is identical to the example. Anyone know why this happens/how to fix it?

Setting CMAKE_EXPORT_COMPILE_COMMANDS should not affect vcpkg installation. Vcpkg installs to CMAKE_BINARY_DIR by default so if you've got vcpkg_installed in the project root then either vcpkg install was launched from the project root or VCPKG_INSTALLED_DIR resolved to it.
Such errors (i.e. first configure ok, subsequent broken) usually happen when CMake cache is messed up, especially if path to cmake toolchain has changed without clearing CMake cache.
