我创建了一个个人的C++库，并尝试在另一个程序中使用它。为了创建和编译我的库，我使用以下命令：
cmake -G "Visual Studio 16 2019" -A x64 ..
cmake --build . --config Release --target INSTALL
我对编译和安装没有问题，但在Target-release.cmake中的安装看起来像这样：
#----------------------------------------------------------------
# Generated CMake target import file for configuration "Release".
#----------------------------------------------------------------
# Commands may need to know the format version.
set(CMAKE_IMPORT_FILE_VERSION 1)
# Import target "containers" for configuration "Release"
set_property(TARGET containers APPEND PROPERTY IMPORTED_CONFIGURATIONS RELEASE)
set_target_properties(containers PROPERTIES
IMPORTED_IMPLIB_RELEASE "C:/Program Files (x86)/containers/lib/containers.lib"
IMPORTED_LOCATION_RELEASE "C:/Program Files (x86)/containers/bin/containers.dll"
)
list(APPEND _IMPORT_CHECK_TARGETS containers )
list(APPEND _IMPORT_CHECK_FILES_FOR_containers "C:/Program Files (x86)/containers/lib/containers.lib" "C:/Program Files (x86)/containers/bin/containers.dll" )
# Commands beyond this point should not need to know the version.
set(CMAKE_IMPORT_FILE_VERSION)
据我所见，没有任何异常。我的问题是：在编译和安装期间，没有生成文件
C:/Program Files (x86)/containers/lib/containers.lib。因此，每次尝试使用查找包时，都会出现错误。（这只是针对visual studio生成器，在mingw中工作正常）。以下是我的CMakeLists.txt:cmake_minimum_required(VERSION 3.1)

我的 CMakeLists.txt 缺少什么，以生成 container.lib 文件？
dllexport导出函数/变量了。如果没有导出的符号，.lib文件将不会被创建。（对于共享库而言，.lib实际上是一个 import 文件）。 - Tsyvarev
