CGAL users discussion list

p.s. you can comment out the include_directories(${EIGEN3_INCLUDE_DIR}) directive.

Hello!

What are the contents of your CMakeFiles.txt?

I'm also on 4.10.6-1-ARCH and I used this one two days ago with success for a single file CGAL program:

------

# Created by the script cgal_create_cmake_script
# This is the CMake script for compiling a CGAL application.


project( test_ )

cmake_minimum_required(VERSION 2.8.10)

find_package(CGAL QUIET COMPONENTS Core )

if ( CGAL_FOUND )

  include( ${CGAL_USE_FILE} )
  include_directories(${EIGEN3_INCLUDE_DIR})

  include( CGAL_CreateSingleSourceCGALProgram )

  create_single_source_cgal_program( "test.cpp" )

else()

    message(STATUS "This program requires the CGAL library, and will not be compiled.")

endif()

I don't think the CGAL package is at fault in this case.

Hi all!

I use cgal version 4.9-1

When trying to `cmake` a package (GPlates, currently making AUR package),
that uses the line `include(${CGAL_USE_FILE})`, on my Arch Linux
(4.10.6-1-ARCH) machine I get the following error:
```
CMake Error at src/CMakeLists.txt:86 (include):
   include could not find load file:

     /usr/lib/CGAL/lib64/CGAL/UseCGAL.cmake
```

This is because `UseCGAL.cmake` is located in `/usr/lib/CGAL`, and not in
that subdirectory.

The directory seems to be set with the variable `CGAL_MODULES_DIR`, which is
set in `/usr/lib/CGAL/UseCGAL.cmake` by the line
`set(CGAL_MODULES_DIR"${CGAL_INSTALL_PREFIX}/lib64/CGAL" )`

But it should be overwritten by these lines in the same file, if I'm
correct.
```
# CGAL_DIR is the directory where this CGALConfig.cmake is installed
string(REPLACE "lib64/CGAL" "" CGAL_INSTALL_PREFIX "${CGAL_CONFIG_DIR}")
```

I've tried to pass `-DCGAL_DIR:PATH=/usr/lib/CGAL` to make cmake command,
but this doesn't fix the issue.

This link describes someone else's trouble with CGAL's dir. It might also
have something to do with the qt4 building that is referred to later on in
the discussion.

Basically my question is: help! I'm confused by if the implementation on my
distro (https://www.archlinux.org/packages/community/x86_64/cgal/) is wrong,
or if I need to make it with qt4, or how I can pass the correct arguments to
cmake, such that it will compile.

Kind regards!

Ilja
