C++ Filesystem functions behave differently in unit tests

[rzblue]

In sim, GetLaunchDirectory, GetOperatingDirectory, and GetDeployDirectory return correctly:

launch: c:\Path\To\Project
operating: c:\Path\To\Project
deploy: c:\Path\To\Project\src\main\deploy

In unit tests, they return directories in the build directory:

launch: c:\Path\To\Project\build\test-results\frcUserProgramTest\windowsx86-64\release
operating: c:\Path\To\Project\build\test-results\frcUserProgramTest\windowsx86-64\release
deploy: c:\Path\To\Project\build\test-results\frcUserProgramTest\windowsx86-64\release\src\main\deploy

Looks like gradle sets the working directory to \build\test-results\frcUserProgramTest\{platform}\{buildType}.

Setting the working directory to the 5th parent directory in unit tests appears to work as a workaround:

std::error_code ec;
std::filesystem::current_path(std::filesystem::current_path().parent_path().parent_path().parent_path().parent_path().parent_path(), ec);
