How to create _just_ the C++ library visr_bear?

[trevorknight]

In the README it says:

visr_bear: a real-time C++ implementation of the BEAR, using libear and VISR. It has a C++ API that makes it reasonably straightforward to embed into other applications; see visr_bear/include/api.hpp

If I am only interested in using bear to render in a different C++ library, is there a easier shortcut to just building that as a static lib without all the python bindings and whatnot? The visr_bear/CMakeLists.txt seems to still have Python bindings and be quite complicated.

Thanks for your time and help!

Hi,

I'm not sure there's a shortcut as such, it's unfortunately a bit of a complicated thing to get right. They are generally amenable to a standard cmake configure/install process, though.

The python bindings can be disabled by disabling BUILD_PYTHON_BINDINGS,

The EAR production suite has some cmake code to build visr and visr_bear as cmake subprojects (so as a user you don't need to have them installed), starting here: https://github.com/ebu/ear-production-suite/blob/e14ba77ca3c77de5c62b99a22dd74819a37c57b3/submodules/CMakeLists.txt#L84

Most of the complexity comes from VISR. We've tried to improve it over the years, but it's always hard because there are a lot of hidden requirements. One thing we could do id provide some vcpkg definitions for visr and visr_bear, I'll have a look into that.
