Fixed it by
$ sudo cp /usr/lib/x86_64-linux-gnu/hdf5/serial/libhdf5.so /usr/local/lib/libhdf5.so
$ sudo cp /usr/lib/x86_64-linux-gnu/hdf5/serial/libhdf5_hl.so /usr/local/lib/libhdf5_hl.so
$ make

Closing this resolved usage/installation issue.

From https://github.com/BVLC/caffe/blob/master/CONTRIBUTING.md:

Please do not post usage, installation, or modeling questions, or other requests for help to Issues.
Use the caffe-users list instead. This helps developers maintain a clear, uncluttered, and efficient view of the state of Caffe.

This is still a code issue and not a "usage/installation" one. Please reopen.

Hi, I edited the dependencies.cmake file with the edits you gave, but when I run makepkg the file gets overwritten again. How do I stop this?

[intelfx]

@kwotsin: run makepkg -so (install deps & extract sources), patch sources, then run makepkg -ei (do not extract sources, build & install).

@longjon Hi, I have copied two files to the /usr/local/lib, but cannot solve this issue. Is there anything I have to pay attention to? Thank you so much.

[jakirkham]

Did you apply the patch from PR ( #4516 ), @bragilee ?

[Abdul-Mukit]

I followed Fazecast@942d22d
provided above. It seems to work.

[ghost]

well...it doesn't work on me,
and I solved it by modifying the file <your_caffe_root>/cmake/Dependencies.cmake as following:

---[ HDF5
find_package(HDF5 COMPONENTS HL REQUIRED)
include_directories(SYSTEM ${HDF5_INCLUDE_DIRS} ${HDF5_HL_INCLUDE_DIR})
list(APPEND Caffe_LINKER_LIBS ${HDF5_LIBRARIES})
list(APPEND Caffe_LINKER_LIBS ${HDF5_HL_LIBRARIES}) #added
