questions about cmake

[Guo-Shuai]

I have build bulllet physics according to the guide on the website of Bullet. But how to set the Bullet_inlcude_dir when cmake Ane_stent. I have tried some path. But none of them works.
The error :
Could NOT find Bullet (missing: BULLET_MATH_LIBRARY)
CMake Error at CMakeLists.txt:16 (message):
message called with incorrect number of arguments

Could you please help me out?

If you did "sudo make install" the include dir should be /usr/local/include/bullet
The field BULLET_MATH_LIBRARY must have the location of the libLinearMath.a or libLinearMath.so. In my case, it is /usr/local/lib/libLinearMath.a

Take into account that for this to work, after you have Bullet Physics compiled, you need to run sudo make install inside Bullet's build directory first.

You can also find the .so/.a files inside Bullet's build directory, and pass each one of them to CMake, just like @jquinterog shows (except with the path inside said build directory, since the /usr/local/lib... path works when Bullet is installed), in case you don't want to install Bullet Physics.

The OS you run matters a bit for the CMake to work. So far this project has been tested on Ubuntu Linux 16 and MacOS High Sierra.

For the project to work you need VTK installed. We have tested version 8.1. You can find it here.

Some versions of Bullet Physics might not work, we tested with version 2.86 which you can download here.

Sorry for not including proper documentation yet, so far we have it in Spanish in our university website, since this is our graduation project.

Oh, I build bullet in win10, and I tried to build the project in win10. And maybe there are some differences. I do not have that path. I will try to build in ubuntu. Thank you very much for your answer.

hello, I tried to build it on ubuntu16.04
I build vtk8.1 and bullet3-2.86, but I got an error when make the ane-stent.

/usr/local/include/vtk-8.1/vtkSmartPointer.h: In instantiation of ‘static vtkSmartPointer vtkSmartPointer::New() [with T = vtkTransform]’:

I do not know how to fix this, could you please help me out?

It worked compiling on OSX, on linux, you must include another library. We have just made a commit with that, so pull the repository and try again.
to execute, you will find in the root directory the file "input.txt". You must execute with that file as a parameter.

I updated the repository and try again, but there is another error in the make progress.

Do you know how to fix it?
