我有一个'int_tester' CMake 项目,它利用ExternalProject_Add
它的'drv' 依赖项。现在,这个“drv”也是使用 CMake 构建的,它在其 include_directories() 中使用父目录。麻烦的是我不知道如何将这个父文件夹复制到里面ExternalProject_Add()
。
目录结构如下:
/
|-common
|-IP
| |-int_tester
| |-drv
drv 的 CMakeLists.txt 看起来像:
add_library(SPT_driver STATIC ${CMAKE_CURRENT_SOURCE_DIR}/src/*.c)
target_include_directories(SPT_driver
PUBLIC ${CMAKE_CURRENT_SOURCE_DIR}/api/
PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/../../common/include/
)
CMakeLists.txt 用于 int_tester,例如:
add_executable(int_tester ...)
ExternalProject_Add(drv_ext
PREFIX ${CMAKE_CURRENT_BINARY_DIR}/drv/drv_dir
URL ${CMAKE_CURRENT_SOURCE_DIR}/../drv
INSTALL_COMMAND ""
)
add_library(drv_import STATIC IMPORTED) #phony lib
add_dependencies (drv_import drv_ext) #link phony lib to the external proj
ExternalProject_Get_Property(drv_ext install_dir) #find out where the external proj is installed
set_property(TARGET drv_import PROPERTY IMPORTED_LOCATION ${install_dir}/src/drv_ext-build/obj/drv.a) #so that the phony lib can have a target
include_directories(${install_dir}/src/drv_ext/api) #and to make current executable dependent on api .h and .a of the externally built lib
target_link_libraries(int_tester drv_import)
可以看到, drv 取决于${CMAKE_CURRENT_SOURCE_DIR}/../../common/include/
.
当'int_tester'构建'drv'(通过ExternalProject_Add
)时,../../common/include/
找不到文件夹(它不是由它带来的ExternalProject_Add
)。即使我为这个公用文件夹添加了另一个伪造的 ExternProject,它的目录结构也不会与CMakeLists.txt
“drv”所期望的目录结构相匹配。
请问我错过了什么?
