Description Steve Robinson 2020-12-25 07:12:11 UTC 
When trying to build 2.0.14 from source on iOS using CMake, I get this error:
SDL_sysurl.m:24:9: fatal error: 'Cocoa/Cocoa.h' file not found
#import <Cocoa/Cocoa.h>

Since this is using Cocoa, I don't think it's meant for iOS. So I fixed it by changing this in CMakeLists.txt:
file(GLOB MISC_SOURCES ${SDL2_SOURCE_DIR}/src/misc/macosx/*.m)
set(SOURCE_FILES ${SOURCE_FILES} ${MISC_SOURCES})
set(HAVE_SDL_MISC TRUE)

To:
if(NOT IOS)
  file(GLOB MISC_SOURCES ${SDL2_SOURCE_DIR}/src/misc/macosx/*.m)
  set(SOURCE_FILES ${SOURCE_FILES} ${MISC_SOURCES})
  set(HAVE_SDL_MISC TRUE)
endif()

Environment:
CMake: 3.19.2
Xcode: 12.3
macOS: 11.1

I _think_ the fix should be like in the following patch:

diff --git a/CMakeLists.txt b/CMakeLists.txt
--- a/CMakeLists.txt
+++ b/CMakeLists.txt
@@ -1670,7 +1670,11 @@
     message_error("SDL_FILE must be enabled to build on MacOS X")
   endif()
 
-  file(GLOB MISC_SOURCES ${SDL2_SOURCE_DIR}/src/misc/macosx/*.m)
+  if(IOS OR TVOS)
+    file(GLOB MISC_SOURCES ${SDL2_SOURCE_DIR}/src/misc/ios/*.m)
+  else()
+    file(GLOB MISC_SOURCES ${SDL2_SOURCE_DIR}/src/misc/macosx/*.m)
+  endif()
   set(SOURCE_FILES ${SOURCE_FILES} ${MISC_SOURCES})
   set(HAVE_SDL_MISC TRUE)

Yup, that's a way better fix. Verified that it worked. Thanks!
