CMake配置src/include结构C++项目遇xtensor头文件缺失问题求助

我在为如下目录结构的C++项目编写CMakeLists.txt时遇到编译错误，主文件为solver_fullyParallelized_shtns_3D.cpp：

2 directories, 19 files

src目录下部分.cpp文件包含#include <xtensor/xarray.hpp>，我已为可执行文件TDSE_solver配置了xtensor相关头文件路径，但编译时出现错误：

distribution_fns.cpp:7:10: fatal error: xtensor/xarray.hpp: No such file or directory
    7 | #include <xtensor/xarray.hpp> 

当前完整CMakeLists.txt如下：

请问哪里配置错误？该如何解决？

错误原因 #

你仅为可执行文件TDSE_solver添加了xtensor头文件路径，但编译静态库（如distribution_fns）时，CMake不会自动继承可执行文件的依赖配置。这些静态库的源文件需要xtensor头文件，但编译阶段无法找到对应路径，因此报错。

解决方案 #

有两种简洁的修复方式，任选其一即可：

方式一：为所有静态库统一配置头文件路径 #

通过定义公共变量共享依赖配置，避免重复代码：

# 定义公共包含目录
set(PUBLIC_INCLUDES
    include
    "/work/e281/e281/ouatu_i/trial_Carrays_IntelMKL_Xtensor_SHTNS_CrayFFTW/xtensor_all/xtensor_install_dir/include/"
    "/work/e281/e281/ouatu_i/trial_Carrays_IntelMKL_Xtensor_SHTNS_CrayFFTW/xtensor_all/xtl_install_dir/include/"
    "/work/e281/e281/ouatu_i/TDSE_3D_Telnov/xtensor_io_install/include/"
)

# 为可执行文件设置
add_executable(TDSE_solver src/solver_fullyParallelized_shtns_3D.cpp)
target_include_directories(TDSE_solver PUBLIC ${PUBLIC_INCLUDES})

# 为每个静态库设置
add_library(absorber_fns STATIC src/absorber_fns.cpp)
target_include_directories(absorber_fns PUBLIC ${PUBLIC_INCLUDES})

add_library(distribution_fns STATIC src/distribution_fns.cpp)
target_include_directories(distribution_fns PUBLIC ${PUBLIC_INCLUDES})

# 其余静态库按上述格式添加target_include_directories配置

方式二：直接将所有源文件编译进可执行文件（更简便） #

利用已定义的SOURCES变量，将所有源文件直接传入add_executable，无需单独创建静态库，所有源文件将共享可执行文件的头文件配置：

# 替换原有的add_executable和静态库创建代码
add_executable(TDSE_solver ${SOURCES})
target_include_directories(TDSE_solver PUBLIC include)

# xtensor配置保持不变
target_include_directories(TDSE_solver PUBLIC "/work/e281/e281/ouatu_i/trial_Carrays_IntelMKL_Xtensor_SHTNS_CrayFFTW/xtensor_all/xtensor_install_dir/include/")
target_include_directories(TDSE_solver PUBLIC "/work/e281/e281/ouatu_i/trial_Carrays_IntelMKL_Xtensor_SHTNS_CrayFFTW/xtensor_all/xtl_install_dir/include/")
target_include_directories(TDSE_solver PUBLIC "/work/e281/e281/ouatu_i/TDSE_3D_Telnov/xtensor_io_install/include/")

# OpenMP链接配置保持不变
if(OpenMP_CXX_FOUND)
target_link_libraries(TDSE_solver PUBLIC OpenMP::OpenMP_CXX)
endif()

这种方式省去了创建多个静态库的步骤，适合中小型项目，所有源文件将使用相同的头文件路径与编译选项。
