@nicolasvilla: ~No it shouldn't. The issue was related to openmvg FindFlann.cmake not utilizing flanns pkg-config script which exports libraries that needs to be linked alongside flann(external) (mainly flann_cpp,lz4, see /usr/lib/pkgconfig/flann.pc#Libs). Check CMakeCache.txt if lz4 flag is in openMVG_matching_LIB_DEPENDS variable (this is sourced from PC_FLANN_LIBRARIES:INTERNAL=flann;flann_cpp;lz4).~

Edit: find the issue in flann package, have it fixed on my os for a long time and forgot to report to the maintainer, I made some temporary changes till flann gets patched...

Hi. I still cannot compile OpenMVG on my machine. OpenMVG build is still using FLANN: 1.9.1 (external) Does it requires an additional patch regarding the undefined LZ4.... messages?

@Harvie: * lz4: problem lays in FindFlann.cmake {flann.patch} see this issue: https://github.com/openMVG/openMVG/issues/1265. I made a pull-req addressing this issue, think I can include it as a patch since pull-req gets through.

Author of OpenMVE suggests us to use the internal version of FLANN. You can force to use the internal one by removing the flann from your depends array and remove the DFLANN_INCLUDE_DIR_HINTS.

Cmake says "** Build OpenCV+OpenMVG samples programs: OFF". Is it possibly reason, why openMVG/src/software/ isn't built? I've posted this question to upstream https://github.com/openMVG/openMVG/issues/1273

Please build and include scripts from openMVG/src/software/ directory of git.

Especially these two are super important to build and include in package:

openMVG/src/software/SfM/SfM_GlobalPipeline.py.in openMVG/src/software/SfM/SfM_SequentialPipeline.py.in

Had to add -llz4 to LDFLAGS in order to build.

Can't build this
