pkg-config Windows

Hi,

I’m trying for the first time the meson build system. Get it working on linux is easy but on Windows I’m a little bit stuck.

My project depends on protobuf.

Meson seems to use pkg-config to test the presence of dependency but where to find the latest pkg-config for Windows ? I’m getting the error : ERROR: Pkg-config not found.
Once I have installed the pkg-config, it will be a certainty that the protobuf library will not be available on the OS. So, which Windows compatible package manager should I install ?
- vc-pkg ?
- Chocolatey ?
- No one as no package manager on Windows can provide *.pc file ?

Best regards,

The good news is that I finally found a way to get cpp compiler of meson (VS) able to find the library with no pkg-config file. The trick is to set the LIB environment variable before calling meson.

In my case

# Open a Visual Studio command prompt and type
> set LIB=%LIB%;d:\vcpkg\installed\x86-windows\\lib;
> mkdir build && cd build
> meson ..

Other alternative is

meson .. "-Dcpp_link_args=/LIBPATH:d:\\installed\\x86-windows\\lib" --backend vs2015

This way, the compiler cl.exe will try to find the library in installed folder of vc-pkg. But I have to make an exception for Windows vs Unix.

if build_machine.system() == 'windows'
  cpp = meson.get_compiler('cpp')
  zlib = cpp.find_library('zlib')
  sodium = cpp.find_library('libsodium')
else
  zlib = dependency('zlib', version: '>=1.2')
  sodium = dependency('libsodium', version: '>=1.0')
endif
protobuf = dependency('protobuf', version: '>=3.0')

This is not a perfect solution, but I hope this will help someone else.

Obviously, it would be much simpler if vcpkg would provides the pkg-file. I’ll see if I can find time to do a PR, but seriously I’m pretty new with cmake.

Writing custom .pc files is pretty straight forward, you can set PKG_CONFIG_PATH to a local directory and include the pc files in your version control for Windows.
