成功建造后缺少二进制文件？
我有一个用于生成Visual Studio解决方案的CMAKE项目，然后尝试编译。由于某种原因，编译后的库文件不存在。我已经搜索了整个项目文件夹，找不到任何库文件。这是我的cmake设置：
项目根：
cmake_minimum_required(VERSION 3.22)
project(ShadowContainers)
set(CMAKE_CXX_STANDARD 23)
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR})
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR})
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR})
include_directories(include/)
add_subdirectory(library)
...
库子目录：
add_library(libShadows shadows.tpp ../include/shadows.hpp)
set_target_properties(libShadows PROPERTIES LINKER_LANGUAGE CXX) # a tpp and an hpp aren't enough to make the system certain it's c++
target_compile_features(libShadows PRIVATE cxx_std_23)
MSBUILD输出包含以下行：
Done Building Project "C:\Users\[..]\projects\Shadow Array\library\libShadows.vcxproj" (default targets).
Done Building Project "C:\Users\[..]\projects\Shadow Array\library\libShadows.vcxproj.metaproj" (default targets).
即使libshadows是我项目中唯一的目标，它在我的项目目录中无处可寻。
还有其他人有这种经历吗？任何帮助都将受到赞赏。谢谢！
编辑： 为了编译项目，我尝试了：
我的典型过程（Working Directory =项目root）：
cmake .
msbuild ShadowContainers.sln
替代过程（工作目录也是项目root）：
mkdir build
cd build
cmake ..
cmake --build .
两者都产生了相同的结果，尽管在不同地方使用VS和CMAKE文件。任何一种方式都没有输出库。
I have a CMake project that I use to generate a Visual Studio solution, which I then try to compile. For some reason, the library file after compilation is nonexistent. I've searched my entire project folder, and cannot find any library files. Here's my CMake setup:
Project root:
cmake_minimum_required(VERSION 3.22)
project(ShadowContainers)
set(CMAKE_CXX_STANDARD 23)
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR})
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR})
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR})
include_directories(include/)
add_subdirectory(library)
...
library subdirectory:
add_library(libShadows shadows.tpp ../include/shadows.hpp)
set_target_properties(libShadows PROPERTIES LINKER_LANGUAGE CXX) # a tpp and an hpp aren't enough to make the system certain it's c++
target_compile_features(libShadows PRIVATE cxx_std_23)
The MSbuild output contains these lines:
Done Building Project "C:\Users\[..]\projects\Shadow Array\library\libShadows.vcxproj" (default targets).
Done Building Project "C:\Users\[..]\projects\Shadow Array\library\libShadows.vcxproj.metaproj" (default targets).
Even if libShadows is the only target in my project, it's nowhere in my project directory.
Has anybody else had this experience? Any help is appreciated. Thanks!
Edit:
To compile the project, I have tried:
My typical process (working directory = the project root):
cmake .
msbuild ShadowContainers.sln
An alternate process (working directory also project root):
mkdir build
cd build
cmake ..
cmake --build .
Both have produced the same result, albeit with VS and CMake files in different places. No library is outputted either way.

我能够找到这个问题。 cmake（以及此事的约定）没有将.TPP视为代码文件（与他们处理标头文件的方式类似）。因此，我试图在没有合法代码文件的情况下编译目标。仅模板的库根本不是库，因此我不应该尝试编译该独立的库，而应该将.HPP和.TPP放在我的项目中！
I was able to find the issue. CMake (and conventions for that matter) do not see a .tpp as a code file (similarly to how they treat header files). Thus, I was trying to compile a target with no legitimate code files. Template-only libraries are not libraries at all, so I should not be attempting to compile this standalone, and should instead put the .hpp and .tpp as the include in my projects!
