libigl not found when "cmake" to libigl on amazon linux

Question

I tried install libigl. Although in this tutorial, it says that it does not need installation, my program not found the libraries.

In my local machine with Ubuntu, cmake works fine!

But in Amazon Linux, instance of EC2 not working.

I compile my project with:

cmake3 .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH=~/out

And the Error is:

CMake Error at CMakeLists.txt:21 (message):
  libigl not found --- You can download it using:

   git clone --recursive https://github.com/libigl/libigl.git /home/ec2-user/closer-lambda/../libigl

closer-lamba is the folder of my c++ project

I tried with git clone, and copy paste library from my original project in Ubuntu to Amazon Linux (to into folder project, ec2-user folder, etc), but always I receive the same error.

My CMakeLists.txt :

cmake_minimum_required(VERSION 3.5)

include_directories(includes)

I think to should compile libigl, but i tried and library blas not found.

Thank you!!!!

Answer 1

I fixed it

I forget copy the "cmake" folder, its contain:

"FindLIBIGL.cmake" in my case, libigl is in logal_libigl

 # - Try to find the LIBIGL library
# Once done this will define
#
#  LIBIGL_FOUND - system has LIBIGL
#  LIBIGL_INCLUDE_DIR - **the** LIBIGL include directory
#  LIBIGL_INCLUDE_DIRS - LIBIGL include directories
#  LIBIGL_SOURCES - the LIBIGL source files
if(NOT LIBIGL_FOUND)

    FIND_PATH(LIBIGL_INCLUDE_DIR igl/readOBJ.h
            ${PROJECT_SOURCE_DIR}/local_libigl/libigl
            ${PROJECT_SOURCE_DIR}/local_libigl/libigl/include
            )


    if(LIBIGL_INCLUDE_DIR)
        set(LIBIGL_FOUND TRUE)
        set(LIBIGL_INCLUDE_DIRS ${LIBIGL_INCLUDE_DIR}  ${LIBIGL_INCLUDE_DIR}/../external/Singular_Value_Decomposition)
        #set(LIBIGL_SOURCES
        #   ${LIBIGL_INCLUDE_DIR}/igl/viewer/Viewer.cpp
        #)
    endif()

endif()
