The vcpkg must not installed in source directory!

this files will be used from doxygen and clang-tidy:

There's a way to ignore the generation of documentation for the vcpkg dependencies: https://github.com/aminya/project_options/blob/72832cab55ef259989fa88378d8954bfc9ceac0b/src/Doxygen.cmake#L36

but each preset has its own binaryDir:

bash-5.2$ grep -rw DOXYGEN_EXCLUDE_PATTERNS 
./build/developer/_deps/_project_options-src/src/Doxygen.cmake:  if(NOT DOXYGEN_EXCLUDE_PATTERNS)
./build/developer/_deps/_project_options-src/src/Doxygen.cmake:    set(DOXYGEN_EXCLUDE_PATTERNS "${CMAKE_CURRENT_BINARY_DIR}/vcpkg_installed/*"
./build/RelWithDebInfo/_deps/_project_options-src/src/Doxygen.cmake:  if(NOT DOXYGEN_EXCLUDE_PATTERNS)
./build/RelWithDebInfo/_deps/_project_options-src/src/Doxygen.cmake:    set(DOXYGEN_EXCLUDE_PATTERNS "${CMAKE_CURRENT_BINARY_DIR}/vcpkg_installed/*"
./build/Release/_deps/_project_options-src/src/Doxygen.cmake:  if(NOT DOXYGEN_EXCLUDE_PATTERNS)
./build/Release/_deps/_project_options-src/src/Doxygen.cmake:    set(DOXYGEN_EXCLUDE_PATTERNS "${CMAKE_CURRENT_BINARY_DIR}/vcpkg_installed/*"

Again a reason why it is recommended to have binaryDir NOT inside the sourceDir.
