正如我在評論中所說,這是我們如何做到這一點的一個例子.

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" )

# ---------- Setup output Directories -------------------------

SET (CMAKE_LIBRARY_OUTPUT_DIRECTORY

${YourSoftwarePath}/lib64

CACHE PATH

"Single Directory for all Libraries"

)

# --------- Setup the Executable output Directory -------------

SET (CMAKE_RUNTIME_OUTPUT_DIRECTORY

${YourSoftwarePath}/bin64

CACHE PATH

"Single Directory for all Executables."

)

# --------- Setup the Executable output Directory -------------

SET (CMAKE_ARCHIVE_OUTPUT_DIRECTORY

${YourSoftwarePath}/lib64

CACHE PATH

"Single Directory for all static libraries."

)

ELSE( EX_PLATFORM EQUAL 64 )

# ---------- Setup output Directories -------------------------

SET (CMAKE_LIBRARY_OUTPUT_DIRECTORY

${YourSoftwarePath}/lib

CACHE PATH

"Single Directory for all Libraries"

)

# --------- Setup the Executable output Directory -------------

SET (CMAKE_RUNTIME_OUTPUT_DIRECTORY

CACHE PATH

)

# --------- Setup the Executable output Directory -------------

SET (CMAKE_ARCHIVE_OUTPUT_DIRECTORY

${YourSoftwarePath}/lib

CACHE PATH

"Single Directory for all static libraries."

)

ENDIF( EX_PLATFORM EQUAL 64 )

...

add_library(YourSoftware SHARED

${INCLUDES}

${SRC}

)

它對我們來說效果很好,即使在我們的生產過程中也是如此.

它允許top為我們的配置做好準備：32位和64位.之后我們必須在兩個平臺上構建.

總結
