[CMake] cmake 3.12 - python libs / 32 / 64 bits

[Stéphane Ancelot]

Hi,

My system is 64 bits but I can cross compile python c modules for 32 bits .

Unfortunately I don't manage to retrieve python 32 libs , always the 64 
bits version is found.


here is what I tried :

cmake_minimum_required(VERSION 3.10)
project(py_autom)


set(CMAKE_SYSTEM_PROCESSOR "i686")

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -m32" CACHE STRING "c++ flags")
set(CMAKE_C_FLAGS   "${CMAKE_C_FLAGS} -m32" CACHE STRING "c flags")

set_property(GLOBAL PROPERTY FIND_LIBRARY_USE_LIB32_PATHS TRUE)
set_property(GLOBAL PROPERTY FIND_LIBRARY_USE_LIB64_PATHS FALSE)

include_directories(python2.6)
find_package(Python2 COMPONENTS Development)



message(STATUS "python ${PYTHON_INCLUDE_DIRS} ${Python2_LIBRARIES_DIR} 
${Python2_FOUND}")

Regards

Steph
