I can't use fgt to accelerate rigid #158

Closed hongyiWeng closed 1 year ago

hongyiWeng commented 1 year ago

I have already donwload fgt from GitHub, and used "cmake" to install it.But when I make example to get fgt,I find that cpd-fgt can't be made.In order to resovle this problem,I add "find_package(Fgt REQUIRED)" in CmakeLists.txt.But when I run make again,the new problem is "‘vtable for cpd::GaussTransformFgt’undeclared".I don't have way to resolve it .If u know how to fix it,please tell me.Thank you.

I was just able to configure/compile/build FGT and CPD locally, so I cannot reproduce. Make sure you are following these steps if you're building from source:

  1. Clone https://github.com/gadomski/fgt
  2. Configure/build/install
  3. Clone https://github.com/gadomski/cpd
  4. Configure/build/install, ensuring that WITH_FGT is ON in the CMakeCache and that Fgt_DIR is a sensible location.
