Now build system looks more maintanable.
I test with mac, going to test with other platforms.
* All prebuilt libs config moved to
cmake/Modules/CocosUsePrebuiltLibs.cmake
* Wrap plain find_package to our cocos_find_package. It will not try to
call find_package if USE_PREBUILT_LIBS and <pkg>_FOUND set to true.
* Other small fixes.
when call 'scheduleUpdate' and 'unscheuleUpdate' several times in one frame, it will get warning "warning: you CANNOT change update priority in scheduled function"
1. Add cmake module for finding minizip in system
2. Check that system installed minizip recent enough for us
3. As right minizip exists only for MSYS2 (mingw), use our embedded version on all other platforms
4. Correctly include minizip as <minizip/unzip.h> if it is found from system (make it compatible to current build system, so by default all should stay same)
5. Remove one unused include of unzip.h
* should be included as simple "tinyxml2.h", but on some files was "tinyxml2/tinyxml2.h", replace this.
* Add cmake/Modules/FindTinyXML2.cmake
* As tinyxml2 for now has not prebuilt, instead sources included, add their as subdirectory if USE_PREBUILT_LIBS
* cmake/Modules/FindChipmunk.cmake now can find prebuilt chipmunk libs
* follow USE_CHIPMUNK variable (although at the moment cocos can't build without chipmunk)
* come cleanups and formatting
* Introduce config variable USE_WEBP (ON by default, but disabled for unsupported archs WINRT and WP8)
* Set CC_USE_WEBP define according to USE_WEBP variable
* add WebP include directories to search patch only for libcocos compilation (it not used in public headers)
* introduce config variable USE_PREBUILT_LIBS (default: ON). When OFF, cmake will not use prebuilt libs, only try find system installed libraries.
* FindGLFW3.cmake now search our prebuilt library (if USE_PREBULT_LIBS)
* FindFreetype.cmake also
This and next changes should simplify our CMakeLists.txt files and USE_PREBUILT_LIBS config allow external package developers to integrate cocos to their packaging system.
Constify arguments to copy constuctors. Without this gcc fail to compile if classes used inside containers.
Error message is rather cryptic: " error: 'constexpr std::pair<_T1, _T2>::pair(const std::pair<_T1, _T2>&) [with _T1 = const int; _T2 = cocos2d::experimental::AudioPlayer]' declared to take const reference, but implicit declaration would take non-const"
Instead of using glfw3 on each required configuration, use it centralized way.
Add our prebuilt location to search paths, so FindGLFW3.cmake can find it also.
