cmake wpilib built without wpilibj still includes it as a dependency in wpilib-config.cmake

[OhmV-IR]

built allwpilib from source using:

1. cmake . --preset default -DBUILD_SHARED_LIBS=OFF -DWITH_GUI=OFF -DWITH_SIMULATION_MODULES=OFF -DWITH_TESTS=OFF
2. sudo cmake --build . --target install --parallel $(nproc)
3. /usr/local/share/wpilib/wpilib-config.cmake still has add_dependency(wpilibj) even though wpilibj was not built due to -DBUILD_SHARED_LIBS=OFF
4. find_package(wpilib REQUIRED) fails because it can't find wpilibj
   expected behavior is that the add_dependency(wpilibj) line is not present if wpilibj was not installed when building the package.
