APR provides CMake targets whose names will start with the 'lib' prefix in shared configurations, while static configurations will not:

find_package(apr CONFIG REQUIRED)

# Use the shared configuration

target_link_libraries(main PRIVATE apr::apr-1 apr::libaprapp-1)

# Use the static configuration

target_link_libraries(main PRIVATE apr::apr-1 apr::aprapp-1)

To ensure compatibility with both static and shared configurations:

find_package(apr CONFIG REQUIRED)

target_link_libraries(main PRIVATE

$<$<TARGET_EXISTS:apr::apr-1>:apr::apr-1>

$<$<TARGET_EXISTS:apr::aprapp-1>:apr::aprapp-1>

$<$<TARGET_EXISTS:apr::libapr-1>:apr::libapr-1>

$<$<TARGET_EXISTS:apr::libaprapp-1>:apr::libaprapp-1>
