我正在尝试使用cmake构建一个子项目(它不是一个xcode项目,甚至不是iphone的应用程序,结果是跨平台的控制台可执行文件,其中#includes一些继承自C++抽象类,用objective-c ++编写)
我正在使用本指南链接mac os框架:http://www.vtk.org/Wiki/CMake: HowToUseExistingOSXFrameworks
而这个宏:
macro(ADD_FRAMEWORK fwname appname)
find_library(FRAMEWORK_${fwname}
NAMES ${fwname}
PATHS ${CMAKE_OSX_SYSROOT}/System/Library
PATH_SUFFIXES Frameworks
NO_DEFAULT_PATH)
if( ${FRAMEWORK_${fwname}} STREQUAL FRAMEWORK_${fwname}-NOTFOUND)
MESSAGE(ERROR ": Framework ${fwname} not found")
else()
TARGET_LINK_LIBRARIES(${appname} ${FRAMEWORK_${fwname}})
MESSAGE(STATUS "Framework ${fwname} found at ${FRAMEWORK_${fwname}}")
endif()
endmacro(ADD_FRAMEWORK)
这是CMakeLists.txt中的重要部分
project(myprojectname)
........
add_executable(mytarget src/mytarget.cpp)
add_framework(CoreMedia mytarget)
add_framework(CoreVideo mytarget)
add_framework(AVFoundation mytarget)
add_framework(Foundation mytarget)
........
这就是我在尝试构建时所拥有的:
