CMAKE:根据生成器类型有条件地初始化缓存变量

我现在有一个基本的Cmake文件,用来设置某些库目录。我想根据目标生成器有条件地初始化——在我的例子中,生成器确定要使用哪个基本目录(64位visual studio生成器与普通visualstudio生成器)。

PROJECT(STAT_AUTH)
CMAKE_MINIMUM_REQUIRED(VERSION 2.8)

SET(BOOST_DIR "c:\\dev_32\\Boost" CACHE PATH "The Boost Directory Path")
SET(PROTOBUF_DIR "c:\\dev_32\\Protobuf" CACHE PATH "The Protobuf directory Path")
SET(OPENSSL_DIR "c:\\dev_32\\OpenSSL" CACHE PATH "The OpenSSL Directory Path"

如何有条件地初始化变量,以便在生成64位生成器时将其设置为64位版本。在选择“generate”选项之前,默认设置应该显示在Cmake Gui/ccmake中。

尝试:

if(CMAKE_SIZEOF_VOID_P MATCHES 4)
  SET(BOOST_DIR "c:\\dev_32\\Boost" CACHE PATH "The Boost Directory Path")
  SET(PROTOBUF_DIR "c:\\dev_32\\Protobuf" CACHE PATH "The Protobuf directory Path")
  SET(OPENSSL_DIR "c:\\dev_32\\OpenSSL" CACHE PATH "The OpenSSL Directory Path"
else()
  SET(BOOST_DIR "c:\\dev_64\\Boost" CACHE PATH "The Boost Directory Path")
  SET(PROTOBUF_DIR "c:\\dev_64\\Protobuf" CACHE PATH "The Protobuf directory Path")
  SET(OPENSSL_DIR "c:\\dev_64\\OpenSSL" CACHE PATH "The OpenSSL Directory Path"
endif()

对于Windows,下面的语法很适合。CMAKE_CL_64专门定义了x86_64编译器。

if(MSVC)
    if(CMAKE_CL_64)
        SET(BOOST_DIR "c:\\dev_64\\Boost" CACHE PATH "The Boost Directory Path")
        SET(PROTOBUF_DIR "c:\\dev_64\\Protobuf" CACHE PATH "The Protobuf directory Path")
        SET(OPENSSL_DIR "c:\\dev_64\\OpenSSL" CACHE PATH "The OpenSSL Directory Path")
        SET(DEPLOY_DIR "c:\\root_64" CACHE PATH "The Deploy Path for the components built" )
    else()
        SET(BOOST_DIR "c:\\dev_32\\Boost" CACHE PATH "The Boost Directory Path")
        SET(PROTOBUF_DIR "c:\\dev_32\\Protobuf" CACHE PATH "The Protobuf directory Path")
        SET(OPENSSL_DIR "c:\\dev_32\\OpenSSL" CACHE PATH "The OpenSSL Directory Path")
        SET(DEPLOY_DIR "c:\\root_32" CACHE PATH 
            "The Deploy Path for the components built" )
    endif()
endif()
