How to Debug configuration with GreeterStandalone in CLion

[navono]

As I opened starter with CLion, I can't find binary in configuration. CLion Settings: CMake: CMake options: -Hall -Bbuild Build directory: build.

Only Greeter and fmt shows in Debug configuration, How to configure to debug the binary module？

[ClausKlein]

-DCMAKE_BUILD_TYPE=Debug should help.

But CLion does not work correctly with an CMake Project.

Try it with Qt-creator, which allow you to change the CMake options and show the Project structure much better!

@ClausKlein thank you for response.

I modify some config in conan_integrate branch in my forked project, standalone and library worked, but test and documentation still failed if add it to root CMakeList.txt

add_subdirectory(app)
add_subdirectory(Greeter)
add_subdirectory(test)
#add_subdirectory(documentation)

with error:

CMake Error at app/CMakeLists.txt:35 (add_executable):
  add_executable cannot create target "App" because another target with the
  same name already exists.  The existing target is an executable created in
  source directory "/mnt/d/sourcecode/cpp/ModernCppStarter/app".  See
  documentation for policy CMP0002 for more details.

any suggestion?

seems like

CPMAddPackage(NAME Greeter SOURCE_DIR ${CMAKE_CURRENT_LIST_DIR}/..)

in test/CMakeList.txt and documentation/CMakeList.txt.

Dit you read the README.md?

The template should be used for a single library project only. If you need to build more than one lib, you should use this template multiple times for each library.

Do not use add_subdirectories()! It can't work with this template.

[navono]

If single header libraries meas CPMAddPackage can only use once, that's sad, it's very unfriendly.

That is neither true nor unfriendly! You can't create with CMake 2 targets with same name.

If you want to change the concept behind the ModernCppStarter Template, it is possible. see for example

But read and understand the CMake Doku!

CPMAddPackage is used within this project. But is independent of it.

That is neither true nor unfriendly!

You're right, because I lack enough understanding of CMake, I will read the Doc and check your example code.

Thank you.
