CGAL integration with CMake using deb package

Question

I want to make a script that uses the CGAL Library having it installed only using the .deb package. (Using: sudo apt-get install libcgal-dev).

I get the following error message when I run this command : cmake -S . -B build/ -DCMAKE_BUILD_TYPE= Release .

I am on an ubuntu 20.04 machine with the following versions:

• g++ 9.4.0
• cmake 3.16

My CMakeLists.txt looks like this:

cmake_minimum_required(VERSION 3.16)

project(integration)

find_package(CGAL)

if ( CGAL_FOUND )

message("CGAL Found !")

endif ( CGAL_FOUND )

add_executable(${PROJECT_NAME} extract_segmentation_into_mesh_example.cpp)

target_link_libraries(${PROJECT_NAME} CGAL::CGAL)

I'm also able to find the directory CGAL in /usr/include/.
