CURLConfig.cmake: find_dependency(NGTCP2 MODULE) missing COMPONENTS crypto backend

[x-xiang]

I did this

When building another library that depends on curl via CURLConfig.cmake, the build fails because NGTCP2 cannot be found without COMPONENTS crypto backend.

find_dependency(NGTCP2 MODULE) missing COMPONENTS crypto backend

ngtcp2_CONFIG being unset

I expected the following

No response

curl/libcurl version

curl 8.20.0

operating system

Linux

This specifically appears in vcpkg because the vcpkg port locks the find modules to a single approach (CMake config or pkgconfig). If CMake config works during build, it shall also work during downstream usage.

IOW "COMPONENTS" is not optional for the CMake config approach, other than documented.
