cmake is not triggered on build command

[Nordsoft91]

• axmol version: axmol-2.1.0-rc7
• devices test on: MacOS M1
• developing environments
  • Xcode version: 14.2
  • cmake version: 3.27.2
    Steps to Reproduce:

1. Create new project
2. Execute axmol build -p osx -a x64 -configOnly
3. Go to build_x64 folder and open .xcodeproj with XCode
4. Create some new .cpp file in Source folder
5. Execute axmol build -p osx -a x64 -configOnly again

Expected: xcode project is updated, new source file is added
Actual: nothing changed, to get actual update you must delete CMakeCache.txt and do full rebuild

If you're using GLOB or GLOB_RECURSE in your project CMakeLists.txt, then that would most likely be the source of the problem, and has nothing to do with Axmol.

Check this section in the file:

file(GLOB_RECURSE GAME_HEADER
    Source/*.h
    )
file(GLOB_RECURSE GAME_SOURCE
    Source/*.cpp
    )

From the CMake docs:

It only takes you a few seconds to manually add a new cpp/h file reference to CMakeLists.txt, so save yourself the hassle and avoid using GLOB/GLOB_RECURSE.

Yes, but CMakeLists.txt is generated by axmol automatically and it's quite big. Possible solution would be to generate short CMakeLists.txt in Source directory automatically which will be much shorter and contain (almost) those lines and include it in root CMakeLists.txt. Thus will be much easier to work with it.

I replaced adding of sources in root CMakeLists.txt:

add_subdirectory(${CMAKE_CURRENT_SOURCE_DIR}/Source)

Now Source/CMakeLists.txt:

# The common cross-platforms source files and header files
file(GLOB_RECURSE GAME_HEADER
    *.h
    )
file(GLOB_RECURSE GAME_SOURCE
    *.cpp
    )

set(GAME_HEADER ${GAME_HEADER} PARENT_SCOPE)
set(GAME_SOURCE ${GAME_SOURCE} PARENT_SCOPE)

Try add param: -force

That is something developers would most likely be doing already, but it may help to add it to the project templates just to make things a little clearer. Consider submitting a PR with the change.
