Describe the bug
Attempting to build wxWidgets via a CMake subproject on my Aegisub Meson port provides the following stack trace:

My system is in Japanese, both locale and OS language. The English equivalent for that error is:
OSError: [WinError 123] The filename, directory name, or volume label syntax is incorrect: 'Q:\\Ryan\\Documents\\GitHub\\Aegisub\\build\\subprojects\\wxWidgets\\__CMake_build\\lib\\vc_x64_dll\\mswu Q:\\Ryan\\Documents\\GitHub\\Aegisub\\subprojects\\wxWidgets\\include'

To Reproduce
Checkout the above repo on the appropriate branch, run meson build from the root from a visual studio command prompt (or something else that will run the setup script for MSVC).

The wx portion in particular:

wx_dep = dependency('wxWidgets', version: '>=3.0.0',
                    required: false,
                    modules: ['std', 'stc', 'gl'])

if wx_dep.found()
    deps += wx_dep
else
    build_shared = 'ON'
    if get_option('default_library') == 'static'
        build_shared = 'OFF'
    endif

    wx = cmake.subproject('wxWidgets', cmake_options: ['-DwxBUILD_INSTALL=OFF',
                                                       '-DwxBUILD_PRECOMP=OFF', # otherwise breaks project generation w/ meson
                                                       '-DwxBUILD_SHARED=@0@'.format(build_shared),
                                                       '-DwxBUILD_MONOLITHIC=ON']) # otherwise breaks project generation w/ meson
    deps += [
        wx.dependency('wxmono'),
        wx.dependency('wxzlib'),
        wx.dependency('wxpng'),
        wx.dependency('wxexpat'),
        wx.dependency('wxregex'),
        wx.dependency('wxscintilla')
    ]

    if host_machine.system() == 'windows'
        if cc.has_header('rpc.h')
            deps += cc.find_library('rpcrt4', required: true)
        else
            error('Missing Windows SDK RPC Library (rpc.h / rpcrt4.lib)')
        endif
        if cc.has_header('commctrl.h')
            deps += cc.find_library('comctl32', required: true)
        else
            error('Missing Windows SDK Common Controls Library (commctrl.h / comctl32.lib)')
        endif
    endif
endif

Expected behavior
CMake subproject succeeds at configure.

system parameters
Native build, win10
Python 3.8.3
Meson 0.56.0
ninja 1.8.2

What CMake version are you using? The Meson-CMake integration works best with CMake >=3.17. Meson has to do a lot more guesswork with CMake <= 3.16 due to missing features in CMake.

Looks like my CMake version is 3.13.3; will update and report back. Thanks for the prompt response!

[CoffeeFlux]

Looks like it succeeds with cmake 3.18.4. Didn't realize I was so out of date. Thanks again!
