[BUG] - put here a short description of the issue

[study313software]

Describe the bug Bug: cmd build error with CGAL 5.4.1 When I compile the project with x64 tools for VS2019: there is a cmake error: CMake Error at code/method/CMakeLists.txt:51 (message):CGAL found, but v5.4 or above is required. Please install CGAL v5.4 or above.

I check the cmake.txt. In line 51,

However, I add the CGAL path to the enviroment. Like This:

And the version of CGAL is 5.4.1 which is >=5.4

Is there anything wrong with my CGAL？ It seemed like the enviroment path don't work

Development/Running environment:

• OS: Windows 10
• Compiler MSVC 2019

Additional context Add any other context about the problem here.

It seems your "${CGAL_VERSION}" is empty. Do you also have other versions of CGAL on your machine? After setting the environment variable, you must restart your VS/CMake for the environment variable to take effect. It is also advised to delete all intermediate files and folders to start a new build.

[study313software]

Yes, I have the lower Version CGAL 4.7 in my computer. Is that effect the build of the project? And I don't put the CGAL 4.7 path in the enviroment.

[LiangliangNan]

Please change:

if (CGAL_FOUND)
    message(STATUS "Found CGAL: ${CGAL_VERSION}")

to

if (CGAL_FOUND)
    message(STATUS "Found CGAL v${CGAL_VERSION}: ${CGAL_INCLUDE_DIRS}")

This will print the include path of the found CGAL (making it easier to identify which version was actually found).

[study313software]

Thanks for your suggestion. I changed the message info. And the include path of the found CGAL is V5.4.1.

But it seemed like the ${CGAL_VERSION} is missing. If I make sure that CGAL is >=5.4.1 in my computer, can I change the line47 in Cmakelists to "if(CGAL_Found)"?

[study313software]

I changed line 47 in cmake. And now it can configure sucess(although missing lib Gurobi) But I don't see any sln or project in release folder? Is there still anything wrong with my build process?

[LiangliangNan]

For the empty ${CGAL_VERSION} variable, where did you get the CGAL code? Did you change anything after you download CGAL?

What commands did you use for the configuration process? I guess you can continue to use "nmake" to build City3D. After that the exe file will be generated in the "bin" directory. To generate project files for a specific IDE like Visual Studio. Please refer to CMake manuals.

Best,

Liangliang

Thanks for your suggestion! When I download CGAL， I follow the tutorial in this link: https://www.cnblogs.com/lmst-ytt/p/16690676.html I changed the gmp folder of CGAL.

With namke, I get exe in the bin folder.

Is the cmake manual means that I could use cmake gui to build the project?

[LiangliangNan]

I meant CMake documentation.

Glad you have successfully built City3D, so I am going to close this issue.

Best,

Liangliang
