Question

I am trying to use cmake to compile darknet for YOLO V3. But I'm getting following error:
CMake Error at C:/Program
Files/CMake/share/cmake-3.16/Modules/FindPackageHandleStandardArgs.cmake:146
(message): Could NOT find PThreads_windows (missing:
PThreads_windows_LIBRARY PThreads_windows_INCLUDE_DIR) Call Stack
(most recent call first): C:/Program
Files/CMake/share/cmake-3.16/Modules/FindPackageHandleStandardArgs.cmake:393
(_FPHSA_FAILURE_MESSAGE) cmake/Modules/FindPThreads_windows.cmake:39
(find_package_handle_standard_args)
C:/Users/MSI/vcpkg/scripts/buildsystems/vcpkg.cmake:288
(_find_package) CMakeLists.txt:93 (find_package)
How can I fix this?

Answer 1

You have defined CMAKE_TOOLCHAIN_FILE as vcpkg. If this variable is defined, darknet will by default think that you have configured pthread_window in vcpkg (it happens at around 30 ~40 lines in CMakeLists.txt), but you actually not.
So you need to replace
if(WIN32 AND NOT DEFINED CMAKE_TOOLCHAIN_FILE)
set(USE_INTEGRATED_LIBS "TRUE" CACHE BOOL "Use libs distributed with this repo")
else()
set(USE_INTEGRATED_LIBS "FALSE" CACHE BOOL "Use libs distributed with this repo")
endif()
by
set(USE_INTEGRATED_LIBS "TRUE" CACHE BOOL "Use libs distributed with this repo")
It will allow darknet to use its own 3rdparty pthreads in the root directory.
