Missing libigl cmake finder in data_preprocessing

[elPistolero]

Thank you for providing the code to your paper.

I noticed that a note in the README is missing that tells the user to clone libigl into data_preprocessing (as in the libigl example project). Furthermore, the cmake finder is missing in data_preprocessing.

This would make it even easier for other researchers to use your code on other datasets.

Hi,

I'm not familiar with cpp. I've cloned libigl in the data_processing folder and as well as cmake it. However when compile data preprocessing I encounter this:
CMake Error at CMakeLists.txt:15 (add_executable):
Target "calc_weight_bin" links to target "igl::opengl" but the target was
not found. Perhaps a find_package() call is missing for an IMPORTED
target, or an ALIAS target is missing?

CMake Error at CMakeLists.txt:15 (add_executable):
Target "calc_weight_bin" links to target "igl::opengl_glfw" but the target
was not found. Perhaps a find_package() call is missing for an IMPORTED
target, or an ALIAS target is missing?
May I ask for some suggestions? Thanks!

Did you "make" & "make install" libigl?

Yes. Could you please provide all the command lines for this step? I'll really appreciate it.

Yes. Could you please provide all the command lines for this step? I'll really appreciate it.

I have tried the following steps, and it works well.

1. clone libigl to data_preprocessing/
2. copy the content of cmake finder to ./data_preprocessing/cmake/FindLIBIGL.cmake
3. execute cmake .
4. execute make
