fatal error: 'CGAL/Simple_cartesian.h' file not found

Issue Details

I've successfully installed CGAL, both from source, using brew or conda. However, I'm not able to include it in my cpp code. I pasted the error message and related CMakeList.txt part as follows. Thank you in advance for any idea!

Source Code

In the CMakeList.txt, I specify the dirs like this:

set(CGAL_DIR /usr/local/lib/cmake)
find_package(CGAL CONFIG REQUIRED)
message(STATUS "Found cgal v${CGAL_VERSION}: ${CGAL_INCLUDE_DIRS}")
message(STATUS "cgal dir: ${CGAL_DIR}")

and during cmake . it gives me

-- Found cgal v5.5.1: /usr/local/include
-- cgal dir: /usr/local/lib/cmake/CGAL

Everything looks fine, but I just get the error message when I'm trying to include CGAL in my code and run make

Environment

• Operating system: Mac, 64 bits
• Compiler: Using /Library/Developer/CommandLineTools/usr/bin/c++ compiler
• Release mode
• CGAL version: 5.5.1
• Boost version: 1.74.0
• Other libraries versions if used: Eigen
• I also used no environments or python venv and conda environments but none of them work.

[lrineau]

In your CMakeLists.txt, after the definition of the target mesh_hole_fill_eric, add a line like that one:

target_link_libraries(mesh_hole_fill_eric PRIVATE CGAL::CGAL)

See the documentation at https://doc.cgal.org/latest/Manual/devman_create_and_use_a_cmakelist.html.
