CMake on OSX

Here I create my first CMakeList for OSX to create a library


cmake_minimum_required(VERSION 2.6)
project (cmakeTest)

set(PROJECT_ROOT $ENV{PROJECT_ROOT})
set(CMAKE_OSX_SYSROOT /Developer/SDKs/MacOSX10.5.sdk)
set(CMAKE_OSX_ARCHITECTURES "i386")

SET(CMAKE_AR ar)
add_definitions( -Wall )

set( CMAKE_ARCHIVE_OUTPUT_DIRECTORY ./CMAKE_build)

set( CMAKE_RUNTIME_OUTPUT_DIRECTORY ./CMAKE_build/bin)

set( CMAKE_LIBRARY_OUTPUT_DIRECTORY ./CMAKE_build/bin)

include_directories(${PLUGIN_ROOT}/cmakeTest/API)

add_definitions(-DMACOSX)
add_library(cmakeTest STATIC
${PROJECT_ROOT}/cmakeTest/src/File1.cpp
${PROJECT_ROOT}/cmakeTest/src/File2.cpp
${PROJECT_ROOT}/cmakeTest/src/File3.cpp
${PROJECT_ROOT}/cmakeTest/src/File4.cpp
${PROJECT_ROOT}/cmakeTest/src/File5.cpp)
