When you install a package you normally get the commands need to be used in your CMakelist.txt to find the installed package but there is nothing when libsecret is installed. Example:

sqlite3 provides CMake targets:

# this is heuristically generated, and may not be correct
find_package(unofficial-sqlite3 CONFIG REQUIRED)
target_link_libraries(main PRIVATE unofficial::sqlite3::sqlite3)
How should I look for libsecret in CMake if installed using vcpkg?
Proposed solution

Generate a target for libsecret so all its dependencies can be linked into a project using libsecret
Describe alternatives you've considered

Individually link all the dependency libraries from libsecret
