CMake:如何为安装不同的目标创建别名？

Question

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:

make install

如何为每个命令分别安装命令？像这样的东西:

make install-static
make install-shared

更新:

还应在需要时安装头文件:

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

Answer 1

将它们分别放在不同的组件中,并为安装设置自定义目标.

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要安装哪些组件.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,则可以使用Development组件另外安装它.
