i want to reduce the generation of *.vcxproj files in visual studio

[jmu201621143028]

i use cmake to creat the project. everything is ok. but it will generate a lot of *.vcxproj files.
this is my dir tree:

    Directory: D:\test

Mode                 LastWriteTime         Length Name
----                 -------------         ------ ----

da---           2025/2/19    17:08                build

-a---           2025/2/19    16:41           8192 main.cpp

the text of CMakeLists.tx

add_executable(demo-absl 
    main.cpp
)

add_subdirectory(${CMAKE_CURRENT_SOURCE_DIR}/abseil-cpp)

target_include_directories(demo-absl PRIVATE
    ${CMAKE_CURRENT_SOURCE_DIR}/abseil-cpp/
)

target_link_libraries(demo-absl PRIVATE
    absl::strings
)

the text of main.cpp

#include <iostream>
#include <string>

#include "absl/strings/str_join.h"

int main() {
  std::vector<std::string> v = {"foo", "bar", "baz"};
  std::string s = absl::StrJoin(v, "-");

  std::cout << "Joined string: " << s << "\n";

  return 0;
}
