visual-studio - CMake - 如何在安装(目标)中安装(目录)？

Question

我的这段代码的目标是将包含文件夹的静态库复制到另一个目录中。

新目录的结构为

output_dir
    ├───include
    ├───lib
         └───win64

我有两行 install 行 CMake 代码，我想将其减少为一行。首先，我将 lib 目标安装到 output_dir/lib/win64 并将 include 目录安装到 output_dir/include。

add_library(lib STATIC test.cpp )

target_include_directories(lib 
    PUBLIC 
        ${PROJECT_SOURCE_DIR}/include
)

install(TARGETS lib
    ARCHIVE
        DESTINATION 
            ${PROJECT_SOURCE_DIR}/build/output_dir/lib/win64
)

install(DIRECTORY
            ${PROJECT_SOURCE_DIR}/include
        DESTINATION
            ${PROJECT_SOURCE_DIR}/build/output_dir/include
)

我想有效地将​​两个安装命令减少为一个，这是我最好的尝试。静态 lib 库被正确复制，但目录被忽略。

install(TARGETS lib
        ARCHIVE
            DESTINATION 
                ${PROJECT_SOURCE_DIR}/build/output_dir/lib/win64
        PUBLIC_HEADER
            DESTINATION
                ${PROJECT_SOURCE_DIR}/build/output_dir/
        INCLUDES
            DESTINATION
                ${PROJECT_SOURCE_DIR}/build/output_dir/     
)

我知道错误出在 public_header，但我做错了什么？

您应该只需要 install() 命令中的 PUBLIC_HEADER 参数，而不是 INCLUDES 参数。但是，您的 PUBLIC_HEADER 参数不会获取任何头文件，因为 PUBLIC_HEADER lib 目标的属性尚未设置。尝试这样的事情:

add_library(lib STATIC test.cpp)

target_include_directories(lib 
    PUBLIC 
        ${PROJECT_SOURCE_DIR}/include
)

# List the headers we want to declare as public for installation.
set(MY_PUBLIC_HEADERS
    ${PROJECT_SOURCE_DIR}/include/MyHeader.hpp
    ${PROJECT_SOURCE_DIR}/include/MyHeader2.hpp
    ...
)

# Tell the target these headers are "public".
set_target_properties(lib PROPERTIES PUBLIC_HEADER "${MY_PUBLIC_HEADERS}")

install(TARGETS lib
    ARCHIVE
        DESTINATION ${PROJECT_SOURCE_DIR}/build/output_dir/lib/win64
    PUBLIC_HEADER
        DESTINATION ${PROJECT_SOURCE_DIR}/build/output_dir   
)
