CMake: 크로스 컴파일을 하자

이런 파일을 만들고

[filename] toolchain.arm.cmake

SET(CMAKE_C_COMPILER /usr/local/arm/4.3.1-eabi-armv6/usr/bin/arm-linux-gcc)

SET(CMAKE_CXX_COMPILER /usr/local/arm/4.3.1-eabi-armv6/usr/bin/arm-linux-g++)

SET(CMAKE_LINKER /usr/local/arm/4.3.1-eabi-armv6/usr/bin/arm-linux-ld)

SET(CMAKE_NM /usr/local/arm/4.3.1-eabi-armv6/usr/bin/arm-linux-nm)

SET(CMAKE_OBJCOPY /usr/local/arm/4.3.1-eabi-armv6/usr/bin/arm-linux-objcopy)

SET(CMAKE_OBJDUMP /usr/local/arm/4.3.1-eabi-armv6/usr/bin/arm-linux-objdump)

SET(CMAKE_RANLIB /usr/local/arm/4.3.1-eabi-armv6/usr/bin/arm-linux-ranlib)

이렇게 실행합니다.

$ cmake -DCMAKE_TOOLCHAIN_FILE=toolchain.arm.cmake .
