正如我在评论中所说,这是我们如何做到这一点的一个例子.

if( CMAKE_SIZEOF_VOID_P EQUAL 8 )

MESSAGE( "64 bits compiler detected" )

SET( EX_PLATFORM 64 )

SET( EX_PLATFORM_NAME "x64" )

else( CMAKE_SIZEOF_VOID_P EQUAL 8 )

MESSAGE( "32 bits compiler detected" )

SET( EX_PLATFORM 32 )

SET( EX_PLATFORM_NAME "x86" )

endif( CMAKE_SIZEOF_VOID_P EQUAL 8 )

...

IF( EX_PLATFORM EQUAL 64 )

MESSAGE( "Outputting to lib64 and bin64" )

SET (CMAKE_LIBRARY_OUTPUT_DIRECTORY

CACHE PATH

ELSE( EX_PLATFORM EQUAL 64 )

ENDIF( EX_PLATFORM EQUAL 64 )

...

add_library(YourSoftware SHARED

${INCLUDES}

${SRC}

)

它对我们来说效果很好,即使在我们的生产过程中也是如此.

它允许top为我们的配置做好准备：32位和64位.之后我们必须在两个平台上构建.
