[cmake] propagate dependencies

are we using the target ZLIB::ZLIB to link with zlib? This is the only case in which we should add find_dependency().
Or it could be another lib we depend on that switched to the modern cmake style but it should be its responsibility to add it in its config file. If we don't have a direct dependency it shouldn't be adding that.

ok i see it's here

AliceVision/src/aliceVision/mvsData/CMakeLists.txt

Line 37 in 6b58d78

ZLIB::ZLIB

While at it we can remove the last two lines with ${ZLIB_INCLUDE_DIR} in AliceVision/src/aliceVision/mvsData/CMakeLists.txt

alicevision_add_library(aliceVision_mvsData
  SOURCES ${mvsData_files_headers} ${mvsData_files_sources}
  PUBLIC_LINKS
    aliceVision_system
    aliceVision_numeric
    aliceVision_image
    ZLIB::ZLIB
    Boost::filesystem
    Boost::boost
    OpenImageIO::OpenImageIO
    OpenImageIO::OpenImageIO_Util
  PUBLIC_INCLUDE_DIRS
   ${ZLIB_INCLUDE_DIR}
)
