Windows Installation: Or tools throwing errors with CMake

[AKASH GUPTA]

Hello Everyone, I have been trying to run OR tools on my Windows machine. I have currently installed Cmake for the building process as the default Makefile is not working with C++ on windows. However, Whenever I try to run

C:\Users\Akash-OMEN\Desktop\or-tools_VisualStudio2022-64bit_v9.3.10497>cmake C:\Users\Akash-OMEN\Desktop\or-tools_VisualStudio2022-64bit_v9.3.10497

The code runs but finally, I get this error:

CMake Error at C:/Program Files/CMake/share/cmake-3.24/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
Could NOT find ZLIB (missing: ZLIB_LIBRARY) (found version "1.2.3")

I have tried to add zlib and zlib_dir but everytime I run the code it throws me the same error again

I need help with this error. Please send me some help

strange the make should work, I'll be happy to have a detailled bug report...

 BTW you should take a look of the CMAKE options
-> https://github.com/google/or-tools/tree/stable/cmake#options

so you can let or-tools build zlib for you instead of trying to find it in your system (which seems not here e.g. you install it using vcpkg or chocolatey)

using -DBUILD_DEPS=ON so your cmake command should be

cmake -S. -Bbuild -DBUILD_DEPS=ON
then
cmake --build build -j 4
