CMake:如何为安装不同的目标创建别名? [英] CMake: How to create alias for installing different targets?

问题描述

假设我有以下库:

add_library(myLib_static STATIC ${SRC_FILES})
add_library(myLib SHARED ${SRC_FILES})

# installing header files
install(FILES ${H_FILES} DESTINATION ${INSTDIRHEADER})

# installing binaries
install(TARGETS myLib_static
         DESTINATION ${INSTDIRBIN})

install(TARGETS myLib
         DESTINATION ${INSTDIRBIN})

如果我执行以下命令，将安装共享和静态库:

If I execute the following command, both shared and static libraries will be installed:

make install

如何为每个命令设置单独的安装命令?像这样:

How can I have separate install commands for each of them? Something like this:

make install-static
make install-shared

更新:

需要时还应安装头文件:

Header files should also be installed when needed:

install(FILES ${H_FILES} DESTINATION ${INSTDIRHEADER})

推荐答案

将它们分别放在不同的组件中，并为安装设置自定义目标.

Put them each in a different component and set up custom targets for the installations.

add_library(foo_static STATIC foo.cpp)
add_library(foo SHARED foo.cpp)

install(TARGETS foo_static
        DESTINATION bin
        COMPONENT static)

install(TARGETS foo
        DESTINATION bin
        COMPONENT shared)

add_custom_target(foo-install
  DEPENDS foo
  COMMAND 
      "${CMAKE_COMMAND}" -DCMAKE_INSTALL_COMPONENT=shared
      -P "${CMAKE_BINARY_DIR}/cmake_install.cmake"
)

add_custom_target(foo_static-install
  DEPENDS foo_static
  COMMAND
     "${CMAKE_COMMAND}" -DCMAKE_INSTALL_COMPONENT=static 
     -P "${CMAKE_BINARY_DIR}/cmake_install.cmake"
)

install(FILES foo.h DESTINATION include COMPONENT static)
install(FILES foo.h DESTINATION include COMPONENT shared)

然后调用自定义目标.

请注意，cpack 使用组件来允许用户安装包来决定安装哪些组件.因此，对于库，标头可能是 Development 组件的一部分.在这种情况下，我们使用共享和静态组件安装标头.如果要以这种方式使用 cpack，那么使用 Development 组件额外安装它可能是有意义的.

Note that components are used by cpack to allow the user installing a package to decide which components to install. So, for a library, the headers might be part of the Development component. In this case we install the header with both the shared and static component. It might make sense to additionally install it with a Development component if cpack is to be used in that way.
