Error while running Gradle Sync on Android Studio projects.

[sarooptech]

• axmol version: 2.5.0
• devices test on: Macbook Air M3
• developing environments
  • NDK version: r23c
  • Xcode version: 14.2+
  • cmake version: The Default that comes configured with 2.5.0 for Android
    Steps to Reproduce:

1. Create a new isolated Axmol project using the command: axmol new -i -p com.example.game -l cpp ExampleGame
2. Open proj.android in Android Studio. You will get an error while importing the project related to PCH adding.

Observations:

• The errors are caused by trying to include precompiled headers in axmol.
• Commenting the following line from ./axmol/core/CMakeLists.txt get's rid of the error but fails while comiling.
  target_precompile_headers(${_AX_CORE_LIB} PRIVATE "$<$<COMPILE_LANGUAGE:CXX>:axmol.h>" )
• I suppose it is trying to include some pre-compiled header files for disabled extensions. It is triggering the error because those headers are not present and are required.

Error: "C/C++ Configuration problem"

[halx99]

does the build success, if so, that should be cmake preheader compile issue, not a axmol issue, just ignore it currently.

[sarooptech]

It does compile and run. Just cmake throwing error while gradle sync. I don't see any problem apart from the error message.
