Se você deseja fazer a compilação cruzada de um programa que usa o CMake para geração dos Makefiles, então você pode declarar o seguinte código no seu CMakeLists.txt :
INCLUDE(CMakeForceCompiler) # this one is important SET(CMAKE_SYSTEM_NAME Linux) set(CMAKE_SYSTEM_PROCESSOR arm) #this one not so much SET(CMAKE_SYSTEM_VERSION 1) # specify the cross compiler SET(CMAKE_C_COMPILER arm-eabi-gcc) SET(CMAKE_CXX_COMPILER arm-eabi-g++) SET(CMAKE_C_FLAGS "-nostdlib -I/workspace/android-imxt-r9.3/external/openssl/include") # where is the target environment SET(CMAKE_FIND_ROOT_PATH /workspace/android-imxt-r9.3/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0) # search for programs in the build host directories SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER) # for libraries and headers in the target directories SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY) SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
