Fix test_gltfio cmake duplicate libs and failed UT.

[suzp1984]

1. Fix the ld test_gltfio duplicated libraries:

[2/2] Linking CXX executable libs/gltfio/test_gltfio
ld: warning: ignoring duplicate libraries: 'filament/libfilament.a', 'libs/filabridge/libfilabridge.a', 'libs/geometry/libgeometry.a', 'libs/ktxreader/libktxreader.a', 'libs/math/libmath.a', 'libs/uberz/libuberzlib.a', 'libs/utils/libutils.a', 'third_party/stb/tnt/libstb.a'

Cause:
the cmake file libs/gltfio/CMakeLists.txt config link_libraries(math utils filament cgltf stb ktxreader geometry tsl trie uberzlib) for the targets includes test_gltfio.

Solution:
clear link_libraries property for test_gltfio target.

set_property(TARGET test_gltfio PROPERTY LINK_LIBRARIES)

2. Fix UT glTFIOTest.AnimatedMorphCubeTransforms

run test_gltfio: ./out/cmake-debug/libs/gltfio/test_gltfio;

with errors:

Expected equality of these values:

    Which is: 64-byte object <00-00 80-3F 00-00 00-00 00-00 00-00 00-00 00-00 00-00 00-00 00-00 80-3F 00-00 00-00 00-00 00-00 00-00 00-00 00-00 00-29 00-00 80-3F 00-00 00-00 00-00 00-00 00-00 00-00 00-00 00-00 00-00 80-3F>

[  FAILED  ] glTFIOTest.AnimatedMorphCubeTransforms (15 ms)

Solution:
use gtest EXPECT_NEAR to compare floats.

Thanks for this. Just out of curiosity, what os+cpu are you running the test on?

[suzp1984]

OS: mac os 13.5.2;
CPU: M2 Arm64 chip;

About the failed UT, it maybe the same issue as #7092 .

The duplicate libraries issue is a recent one on macOS with the latest Xcode. I fixed several CMakeLists.txt last week, I'm surprised I didn't catch this one, so thanks for fixing it!
