You can give any options globally with the new VS_USER_PROPS target property (version >= 3.8).

Here is a working example:

CMakeLists.txt

cmake_minimum_required(VERSION 3.0)

project(SetEnvPathTest)

file(WRITE main.cpp [=[
// http://en.cppreference.com/w/cpp/utility/program/getenv
#include 
#include 

int main()
{
    if(const char* env_p = std::getenv("PATH"))
        std::cout << "Your PATH is: " << env_p << '\n';
}
]=])
add_executable(${PROJECT_NAME} main.cpp)

file(WRITE "${CMAKE_CURRENT_BINARY_DIR}/${PROJECT_NAME}.Cpp.user.props" [=[
 

  
    PATH=C:\Test
  
  
    PATH=C:\Test
  

]=])

set_target_properties(
    ${PROJECT_NAME}
    PROPERTIES
        VS_USER_PROPS "${PROJECT_NAME}.Cpp.user.props"
)
