JsonCpp failed to run "jsoncpp_readerwriter" and "jsoncpp_readerwriter_json_checker" tests on release and debug configuration with MSVC on windows x86 and x64

Hi All,

The MSVC team recently test JsonCpp project and found JsonCpp failed to run "jsoncpp_readerwriter" and "jsoncpp_readerwriter_json_checker" tests on release and debug configuration on Windows_x86 and windows_x64. Below are details of our issue:

Describe the bug
JsonCpp failed to run "jsoncpp_readerwriter" and "jsoncpp_readerwriter_json_checker" tests on release and debug configuration with MSVC on windows x86 and x64. Could you please help look at this issue or provide some workarounds? Thanks in advance.

Expected behavior
For JsonCpp x86 and x64, "jsoncpp_readerwriter" and "jsoncpp_readerwriter_json_checker" tests should be run pass on the windows.

To Reproduce on Windows_x64

1. git clone https://github.com/open-source-parsers/jsoncpp open-source-parsers\jsoncpp  F:\gitP\open-source-parsers\jsoncpp
2. mkdir cd F:\gitP\open-source-parsers\jsoncpp\build_amd64
3. cd cd F:\gitP\open-source-parsers\jsoncpp\build_amd64
4. cmake -G "Visual Studio 16 2019" -A x64 -DCMAKE_SYSTEM_VERSION=10.0.18362.0 -DJSONCPP_WITH_POST_BUILD_UNITTEST=OFF .. 2>&1
5. msbuild /m /p:Platform=x64 /p:Configuration=Release ALL_BUILD.vcxproj /t:Rebuild 2>&1
6. ctest -C Release --output-on-failure 2>&1

Setup
VS 2019 + Windows Server 2019

Additional context
test logs
test.log
test.log.2.out test.log.2.txt

Start by reproducing the failure with the listed CMake, MSBuild, and CTest commands on Windows, then inspect test.log and test.log.2.txt. Focus on the jsoncpp_readerwriter and jsoncpp_readerwriter_json_checker tests across the stated x86/x64 and Debug/Release configurations. Done means both tests pass in all requested configurations.
