Compiler Issues

[pdell-kitware]

CT-ICP is written in C++-17,

This means you need a compiler which support C++17,

To configure the compiler you want before building the project, write the following lines:

export CC=<path-to-c-compiler>
export CXX=<path-to-cxx-compiler>

cmake .. etc..

Thank you for your answer

when I
cd ros/roscore
mkdir cmake-build-release && cd cmake-build-release #< Create the build directory
cmake .. -DCMAKE_BUILD_TYPE=Release
It got the error
