Getting the following output in building step cmake ..
Similar to issue #86. Also updating to the latest master or commit referenced in #86 doesn't seem to help.

CMake Warning at CMakeLists.txt:65 (find_package):
  By not providing "FindBehaviorTree.cmake" in CMAKE_MODULE_PATH this project
  has asked CMake to find a package configuration file provided by
  "BehaviorTree", but CMake did not find one.

  Could not find a package configuration file provided by "BehaviorTree" with
  any of the following names:

    BehaviorTreeConfig.cmake
    behaviortree-config.cmake

  Add the installation prefix of "BehaviorTree" to CMAKE_PREFIX_PATH or set
  "BehaviorTree_DIR" to a directory containing one of the above files.  If
  "BehaviorTree" provides a separate development package or SDK, be sure it
  has been installed.

It seems the to be found package should be called "BehaviorTreeV3" rather than "BehaviorTree". I fixed it by changing the name in line 65 in CMakeLists.txt. Maybe someone can comment on whether this is a valid fix.

I think it is, since this is what the package name has changed from previous versions. I am using catkin, so for me it's looking for behaviortree_cpp_v3 and builds successfully. However, I think people would've noticed this issue by now...

try making a PR and wait for it to be rejected or accepted, but, meanwhile, I think you can roll with your change
