How to build and link google benchmark using cmake in windows

问题

I am trying to build google-benchmark and use it with my library using cmake. I have managed to build google-benchmark and run all its tests successfully using cmake. I am unfortunately unable to link it properly with my c++ code in windows using cmake or cl.

the problem I think is that google-benchmark builds the library inside the src folder, i.e it is build in src/Release/benchmark.lib now i cannot point to it in cmake if I use ${benchmark_LIBRARIES} it looks for the library in the Release folder outside src, as this is the usual place all the libraries are build. and it is difficult to find examples which work in windows.

here are two ways which I have tried, both can build the library and all the tests run but I cannot point to the library to target_link_library properly

include(ExternalProject)
ExternalProject_Add(googlebenchmark
  GIT_REPOSITORY    https://github.com/google/benchmark.git
  GIT_TAG           master
  SOURCE_DIR        "${CMAKE_CURRENT_BINARY_DIR}/googlebenchmark-src"
  BINARY_DIR        "${CMAKE_CURRENT_BINARY_DIR}/googlebenchmark-build"
  CONFIGURE_COMMAND ${CMAKE_COMMAND} -B ${CMAKE_CURRENT_BINARY_DIR}/googlebenchmark-build -S ${CMAKE_CURRENT_BINARY_DIR}/googlebenchmark-src -DBENCHMARK_DOWNLOAD_DEPENDENCIES=ON
  BUILD_COMMAND     ${CMAKE_COMMAND} --build ${CMAKE_CURRENT_BINARY_DIR}/googlebenchmark-build --config Release 
  INSTALL_COMMAND   ""
  TEST_COMMAND      ${CMAKE_CTEST_COMMAND} ${CMAKE_CURRENT_BINARY_DIR}/googlebenchmark-src ${CMAKE_CURRENT_BINARY_DIR}/googlebenchmark-build --build-config Release 
)

and

ExternalProject_Add(googlebenchmark
  GIT_REPOSITORY    https://github.com/google/benchmark.git
  GIT_TAG           master 
  PREFIX            googlebenchmark
  CMAKE_ARGS        -DBENCHMARK_DOWNLOAD_DEPENDENCIES=ON
  BUILD_COMMAND     ${CMAKE_COMMAND} --build . --config Release
  INSTALL_COMMAND   ""
  TEST_COMMAND      ${CMAKE_CTEST_COMMAND} --build-config Release
)

how do i link it to my c++ file try.cpp after this
