CMake同时发现和未发现增强

问题描述

我正在尝试安装 ismrmrd 并遵循Windows的安装指南.

在步骤cmake-gui.exe中，我的cmake找不到安装的Boost.

在CMakeLists.txt中添加这些行之后，结果变得很有趣.

有什么想法吗?

UPDATE 8/21

感谢 vre 和 user1234567

现在我更改为提高1.66，但仍然没有运气.

新的屏幕截图显示FindBoost现在没有抱怨.但是仍然没有发现任何提振.

---

UPDATE 8/22

添加后

cmake_policy(SET CMP0074 NEW)

和

通过 vre

的建议将

set(Boost_USE_STATIC_LIBS ON) set(Boost_USE_MULTITHREADED ON) find_package(Boost REQUIRED system filesystem) include_directories(${Boost_INCLUDE_DIRS}) target_link_libraries(ismrmrd ${Boost_LIBRARIES})转换为CMakeLists.txt

产生的错误成为此屏幕截图

解决方案

由于渴望评论，我尝试提出一个食谱:

仅使用Boost标头/静态库所需的命令是:

set(Boost_ADDITIONAL_VERSIONS 1.66.0 1.66)
set(BOOST_ROOT "C:/local/boost_1_66_0")
set(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_MULTITHREADED ON)

仅使用标头库仅使用

find_package(Boost)

否则，在COMPONENTS关键字之后命名要使用的组件(库)并使用

find_package(Boost COMPONENTS <e.g. filesystem system ...>)

if (Boost_FOUND)
  include_directories(${Boost_INCLUDE_DIRS})
  add_definitions( "-DHAS_BOOST" )
endif()

稍后在调用中仅引用Header Boost引用导入的目标(库)

target_link_libraries(yourproject Boost::boost)

或在调用中用于命名库组件

target_link_libraries(yourproject ${Boost_LIBRARIES})

在对有关Boost和Boost组件的CMakeLists.txt进行更改时，请务必始终删除构建目录中的CMakeCache.txt文件，因为它可能会缓存上一次CMake运行的值.

I am trying to install ismrmrd and following the installation guide for Windows.

In the step cmake-gui.exe my cmake is not finding installed Boost.

After adding those lines to CMakeLists.txt the result became interesting.

Any ideas?

UPDATE 8/21

thanks vre and user1234567

Now I changed to boost 1.66 and still no luck.

The new screenshot shows FindBoost is not complain anything now.But still not any boost found.

---

UPDATE 8/22

After adding

cmake_policy(SET CMP0074 NEW)

and

set(Boost_USE_STATIC_LIBS ON) set(Boost_USE_MULTITHREADED ON) find_package(Boost REQUIRED system filesystem) include_directories(${Boost_INCLUDE_DIRS}) target_link_libraries(ismrmrd ${Boost_LIBRARIES}) into CMakeLists.txt by the suggestion from vre

The resulting error became this screenshot

解决方案

As it is to long for comments I try to come up with a recipe:

The commands needed for using Boost header only/static libraries are:

set(Boost_ADDITIONAL_VERSIONS 1.66.0 1.66)
set(BOOST_ROOT "C:/local/boost_1_66_0")
set(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_MULTITHREADED ON)

For using solely header only libraries use

find_package(Boost)

otherwise name the components (libraries) to be used after the COMPONENTS keyword and use

find_package(Boost COMPONENTS <e.g. filesystem system ...>)

if (Boost_FOUND)
  include_directories(${Boost_INCLUDE_DIRS})
  add_definitions( "-DHAS_BOOST" )
endif()

Later you reference the imported targets (libraries) for header only Boost in a call

target_link_libraries(yourproject Boost::boost)

or for named library components in a call

target_link_libraries(yourproject ${Boost_LIBRARIES})

Be sure to always delete the CMakeCache.txt file in the build directory when making changes to the CMakeLists.txt regarding Boost and Boost components, as it might cache the values of a previous CMake run.
