AUI provides set of AUI_PLATFORM_* and AUI_COMPILER_* definitions for platform and compiler checking to use in both CMake and C++.

Platform checks

Platform	C++	CMake	Platform specific dir
Windows	#if AUI_PLATFORM_WIN // ... #endif	if(AUI_PLATFORM_WIN) # ... endif()	`Platform/win32`
Linux (not Android)	#if AUI_PLATFORM_LINUX // ... #endif	if(AUI_PLATFORM_LINUX) # ... endif()	`Platform/linux`
macOS	#if AUI_PLATFORM_MACOS // ... #endif	if(AUI_PLATFORM_MACOS) # ... endif()	`Platform/macos`
Android	#if AUI_PLATFORM_ANDROID // ... #endif	if(AUI_PLATFORM_ANDROID) # ... endif()	`Platform/android`
iOS (both iPhone and iPad)	#if AUI_PLATFORM_IOS // ... #endif	if(AUI_PLATFORM_IOS) # ... endif()	`Platform/ios`
Apple (macOS, iOS)	#if AUI_PLATFORM_APPLE // ... #endif	if(AUI_PLATFORM_APPLE) # ... endif()	`Platform/apple`
Unix (Linux, Android, macOS, iOS)	#if AUI_PLATFORM_UNIX // ... #endif	if(AUI_PLATFORM_UNIX) # ... endif()	`Platform/unix`
Emscripten	#if AUI_PLATFORM_EMSCRIPTEN // ... #endif	if(AUI_PLATFORM_EMSCRIPTEN) # ... endif()	`Platform/emscripten`

Platform specific sources

With AUI, the platform dependent code can be placed in src/Platform/<PLATFORM_NAME> dir, where <PLATFORM_NAME> is one of the supported platforms (see the table above).

Compiler checks

Compiler	C++	CMake
MSVC	#if AUI_COMPILER_MSVC // ... #endif	if(AUI_COMPILER_MSVC) # ... endif()
GCC (including MinGW)	#if AUI_COMPILER_GCC // ... #endif	if(AUI_COMPILER_GCC) # ... endif()
CLANG	#if AUI_COMPILER_CLANG // ... #endif	if(AUI_COMPILER_CLANG) # ... endif()

Other

AUI_MODULE_NAME

Target name exposed by aui_module and aui_executable.

API_<module name>

dllexport (on Windows) or visibility (on other platforms) policy for the symbol.

class API_AUI_VIEWS AView ... { // defined in aui.views module
  ...
};
