I am familiar with

for windows. I am looking for a solution which is platform independent .I am using boost so preferably something in boost that can be used for both the platforms.

Since you're trying to get the executable's own version, why not just add a #define? For example:


// include guards etc.
#define MY_PROGRAM_VERSION "1.2.3"

To pull the version from your CMakeLists.txt rather than hardcoding, try this:


// include guards etc.


cmake_minimum_required(VERSION 3.0) # Use higher if you need, lower won't work.

project(test VERSION 1.2.3) # The one and only place where you define your version!

configure_file(version.h.template version.h)

I assume you have something like that project(...) line already, to configure the version. Among others, it sets a CMake variable named PROJECT_VERSION.

The configure_file call takes the template, fills in variables that CMake knows about, and writes the output to version.h, which you can #include normally. When either the version or the template changes, CMake will regenerate the file.
