cmake glob包含同时保留目录结构

Question

我是cmake 的新手，我正在尝试安装.hpp 文件，同时保留目录结构。

目前为止

FILE(GLOB files "${CMAKE_CURRENT_SOURCE_DIR}/include/*.hpp"
  "${CMAKE_CURRENT_SOURCE_DIR}/include/MyLib/*.hpp"
  "${CMAKE_CURRENT_SOURCE_DIR}/include/MyLib/detail/*.hpp"

install (FILES ${files}  DESTINATION include)

所有文件都已找到，但目录层次结构已展平。

FWIW 我试图模拟的bjam 命令是

install headers 
    : ../include/EnsembleLearning.hpp  
      [ glob ../include/MyLib/*.hpp ]  
      [ glob ../include/MyLib/detail/*.hpp ]  
    : <install-source-root>../include ;

Answer 1

您可以使用 CMake install 命令的 DIRECTORY 变体。此命令将保留复制目录的结构：

install(DIRECTORY include/ DESTINATION include
          FILES_MATCHING PATTERN "*.hpp")

如果要复制的目录包含不应安装的子目录，则必须使用 PATTERN EXCLUDE 选项明确排除那些：

install(DIRECTORY include/ DESTINATION include
          FILES_MATCHING PATTERN "*.hpp"
          PATTERN "include/MyOtherLib" EXCLUDE)
