CMake、"IMPORTED" 个库和查找脚本

Question

我正在尝试将 MPI 包含在项目中并将其作为导入库添加到我的 CMake 项目中。这是我的代码：

find_package(MPI REQUIRED)
add_library(MPI SHARED IMPORTED)
set_property(TARGET MPI PROPERTY INTERFACE_INCLUDE_DIRECTORIES ${MPI_INCLUDE_PATH})
set_property(TARGET MPI PROPERTY IMPORTED_LOCATION ${MPI_CXX_LIBRARIES})

这给了我以下错误：

clang: error: no such file or directory: '/usr/local/Cellar/open-mpi/1.10.2_1/lib/libmpi_cxx.dylib;/usr/local/Cellar/open-mpi/1.10.2_1/lib/libmpi.dylib'

我认为这是因为 IMPORTED_LOCATION 只是一个文件，而不是 FindMPI.cmake returns。有什么解决办法吗？

Answer 1

使用列表中的第一个元素作为IMPORTED_LOCATION属性，使用其他元素作为INTERFACE_LINK_LIBRARIES 属性:

find_package(MPI REQUIRED)
add_library(MPI SHARED IMPORTED)
set_property(TARGET MPI PROPERTY INTERFACE_INCLUDE_DIRECTORIES ${MPI_INCLUDE_PATH})
# Copy list for prevent its from modification.
set(other_elems ${MPI_CXX_LIBRARIES})
list(GET other_elems 0 first_elem)
list(REMOVE_AT other_elems 0)
set_property(TARGET MPI PROPERTY IMPORTED_LOCATION ${first_elem})
set_property(TARGET MPI PROPERTY INTERFACE_LINK_LIBRARIES ${other_elems})
