Question

我知道如何使用b2命令安装Boost并指定仅安装文件系统库。 Boost目录有许多我不需要的内容，克隆所有子模块需要很长时间。我有这个cmake文件来下载，构建和安装Boost。但我不知道如何在CMakeLists.txt中指定要克隆的子模块。我正在使用ExternalProject_add下载，构建和安装Boost。

cmake_minimum_required(VERSION 2.8)
include(ExternalProject)
# Download boost from git

SET (BOOST_INCLUDE_DIRS ${CMAKE_CURRENT_BINARY_DIR}/boost/src/boost/lib/filesystem/include/boost/)
SET (BOOST_URL https://github.com/boostorg/boost.git )
get_filename_component(BOOST_STATIC_LIBRARIES ${CMAKE_CURRENT_BINARY_DIR}/lib/libboost_filesystem.a ABSOLUTE)

if ( UNIX )     
    SET (BOOST_STATIC_LIBRARIES ${BOOST_BUILD}/libboost_filesystem.a) 
endif ()

ExternalProject_Add(
boost
PREFIX ${CMAKE_CURRENT_BINARY_DIR}/boost
GIT_REPOSITORY ${BOOST_URL}

UPDATE_COMMAND ./bootstrap.sh --with-libraries=filesystem,system 
CONFIGURE_COMMAND ""
BUILD_COMMAND ./b2 link=static install --exec-prefix=${CMAKE_BINARY_DIR}/lib/ --includedir=${CMAKE_BINARY_DIR}/include/boost/
BUILD_IN_SOURCE 1
INSTALL_COMMAND ""
)

set(BOOST_LIBRARIES ${CMAKE_CURRENT_BINARY_DIR}/lib)
message ("${BOOST_STATIC_LIBRARIES}")

修改

我现在有以下CMakeLists.txt文件：

cmake_minimum_required(VERSION 2.8)
include(ExternalProject)
# Download boost from git
SET (BOOST_INCLUDE_DIRS ${CMAKE_CURRENT_BINARY_DIR}/boost/src/boost/lib/filesystem/include/boost/)
SET (BOOST_URL https://github.com/boostorg/boost.git )
get_filename_component(BOOST_STATIC_LIBRARIES ${CMAKE_CURRENT_BINARY_DIR}/lib/libboost_filesystem.a ABSOLUTE)

if ( UNIX )     
    SET (BOOST_STATIC_LIBRARIES ${BOOST_BUILD}/libboost_filesystem.a) 
endif ()

ExternalProject_Add(
boost
PREFIX ${CMAKE_CURRENT_BINARY_DIR}/boost
GIT_REPOSITORY ${BOOST_URL}
GIT_SUBMODULES libs/assert libs/utility libs/config libs/predef libs/system libs/detail libs/filesystem  tools/boostdep tools/build tools/bcp tools/boostbook tools/inspect tools/litre tools/quickbook tools/auto_index
UPDATE_COMMAND ./bootstrap.sh --with-libraries=filesystem,system 
CONFIGURE_COMMAND ./b2 headers
BUILD_COMMAND ./b2 link=static install
CMAKE_ARGS -DCMAKE_INSTALL_PREFIX=${CMAKE_BINARY_DIR}/lib
BUILD_IN_SOURCE 1
INSTALL_COMMAND ""
)

set(BOOST_LIBRARIES ${CMAKE_CURRENT_BINARY_DIR}/lib)
message ("${BOOST_STATIC_LIBRARIES}")

但我收到此错误消息：

...patience...
...found 925 targets...
...updating 337 targets...
common.mkdir /usr/local/include/boost
mkdir: Unable to create directory "/usr/local/include/boost": Permission denied.

    mkdir -p "/usr/local/include/boost"

...failed common.mkdir /usr/local/include/boost...

但是在cmake文件中我使用了这个：

CMAKE_ARGS -DCMAKE_INSTALL_PREFIX=${CMAKE_BINARY_DIR}/lib

安装在与root不同的目录中。但它似乎没有起作用。

编辑2：

我知道如何安装在与root不同的目录中。但似乎还有另一个问题，因为同样的问题发生了。我该怎么办？

我补充说：

UPDATE_COMMAND ./bootstrap.sh --with-libraries=filesystem,system --includedir=${CMAKE_BINARY_DIR}/include/


cmake_minimum_required(VERSION 2.8)
include(ExternalProject)
# Download boost from git
SET (BOOST_INCLUDE_DIRS ${CMAKE_CURRENT_BINARY_DIR}/boost/src/boost/lib/filesystem/include/boost/)
SET (BOOST_URL https://github.com/boostorg/boost.git )
get_filename_component(BOOST_STATIC_LIBRARIES ${CMAKE_CURRENT_BINARY_DIR}/lib/libboost_filesystem.a ABSOLUTE)

if ( UNIX )     
    SET (BOOST_STATIC_LIBRARIES ${BOOST_BUILD}/libboost_filesystem.a) 
endif ()

我是如何解决我的问题的：使用

下载细节子模块

GIT_SUBMODULES选项

使用并在仅安装静态版本

的情况下将boost安装在其他目录中

BUILD_COMMAND ./b2 link = static install --libdir = $ {CMAKE_BINARY_DIR} / lib

并且：使用以下方法安装特定二进制文件：

UPDATE_COMMAND ./bootstrap.sh --with-libraries = filesystem，system，regex，program_options --includedir = $ {CMAKE_BINARY_DIR} / include

cmake_minimum_required ( VERSION 2.8.7 )

# Download boost from git

include(ExternalProject)

if ( UNIX )

   if (NOT Boost)

  SET (Boost_INCLUDE_DIRS ${CMAKE_CURRENT_BINARY_DIR}/include/boost/)
  SET (Boost_LIBRARIES ${CMAKE_CURRENT_BINARY_DIR}/lib )
  SET (BOOST_URL https://github.com/boostorg/boost.git )
  SET (BOOST_BUILD ${CMAKE_CURRENT_BINARY_DIR}) 
  SET (FILESYSTEM_STATIC_LIBRARIES ${BOOST_BUILD}/lib/libboost_filesystem.a) 
  SET (SYSTEM_STATIC_LIBRARIES ${BOOST_BUILD}/lib/libboost_system.a)
  SET (REGEX_STATIC_LIBRARIES ${BOOST_BUILD}/lib/libboost_regex.a)
  SET (PROGRAM_OPTIONS_STATIC_LIBRARIES ${BOOST_BUILD}/lib/libboost_program_options.a)

  ExternalProject_Add( Boost
    PREFIX Boost
    GIT_REPOSITORY ${BOOST_URL}
    GIT_SUBMODULES  libs/asio libs/date_time libs/config libs/core  libs/detail  libs/io libs/iterator libs/predef libs/preprocessor  libs/smart_ptr libs/throw_exception libs/system libs/filesystem  libs/integer tools/build tools/bcp libs/serialization libs/interprocess libs/tokenizer libs/algorithm libs/program_options  libs/regex  libs/static_assert  libs/thread  libs/utility libs/numeric libs/range libs/array libs/bind libs/concept_check libs/lexical_cast libs/math libs/functional libs/assert libs/type_traits libs/mpl libs/move libs/container libs/any libs/type_index libs/function

    UPDATE_COMMAND ./bootstrap.sh --with-libraries=filesystem,system,regex,program_options --includedir=${CMAKE_BINARY_DIR}/include/
    CONFIGURE_COMMAND ./b2 headers
    BUILD_COMMAND ./b2 link=static install --libdir=${CMAKE_BINARY_DIR}/lib
    BUILD_IN_SOURCE 1
    INSTALL_COMMAND ""
  )

  ADD_LIBRARY (Boost_LIB STATIC IMPORTED DEPENDS Boost)  
  SET_TARGET_PROPERTIES (Boost_LIB PROPERTIES IMPORTED_LOCATION ${FILESYSTEM_STATIC_LIBRARIES})
  SET_TARGET_PROPERTIES (Boost_LIB PROPERTIES IMPORTED_LOCATION ${SYSTEM_STATIC_LIBRARIES})
  SET_TARGET_PROPERTIES (Boost_LIB PROPERTIES IMPORTED_LOCATION ${REGEX_STATIC_LIBRARIES})
  SET_TARGET_PROPERTIES (Boost_LIB PROPERTIES IMPORTED_LOCATION ${PROGRAM_OPTIONS_STATIC_LIBRARIES}) 

   endif()
endif()
