#include <vtkVariant.h>

int main(int, char*)
{
double dVal = vtkVariant(“2”).ToDouble();
std::cout << "dVal: " << dVal << std::endl;
// I get the error in following line of code
std::string strVal = vtkVariant(dVal).ToString();
std::cout << "strVal: " << strVal << std::endl;
return EXIT_SUCCESS;
}

Here an example like this compiles

cmake_minimum_required(VERSION 3.13)
project(Variant
LANGUAGES CXX)

# -----------------------------------------------------------------------------
# Handle VTK dependency
# -----------------------------------------------------------------------------

# Enable C++20 for the project
set(CMAKE_CXX_STANDARD 20)
set(CMAKE_CXX_STANDARD_REQUIRED ON)  # Ensure the standard is required.
set(CMAKE_CXX_EXTENSIONS OFF)        # Use only standard-compliant C++.

find_package(VTK
  COMPONENTS
    CommonCore)

if (NOT VTK_FOUND)
  message("Skipping issue: ${VTK_NOT_FOUND_MESSAGE}")
  return ()
endif ()

# -----------------------------------------------------------------------------
# Compile example code
# -----------------------------------------------------------------------------

add_executable(Variant Variant.cxx)

target_link_libraries(Variant
  PRIVATE
    VTK::CommonCore
)

Perhaps, you have an issue linking to debug from a release build or vice versa.
