[BUG] CMake error with "target_compile_definitions" and environment variables

[Subburaj47]

Describe the bug I believe the minimum_required_version in the available CMakes are 2.8. I face a problem with the cmake while cmake runs in 2.8 versions.

1. The cmake function "target_compile_definitions" seems to be an unknown command.
2. "CMAKE_LANGUAGES_COMPILER_ENV_VAR" and "CMAKE_LANGUAGES_COMPILER" modules are not found.

To Reproduce Have a 2.8 version of cmake available in the build system. Checkout the 3.0.0 SDK and trigger the cmake.

Expected behavior CMake would have got executed peacefully and subsequently the build.

SDK version number SDK version used is 3.0.0

Platform (please complete the following information): running in linux.

Additional context Any option other than the cmake version upgrades would help amazon-kinesis-video-streams-producer-sdk-cpp.log .

@Subburaj47 Thanks for the report!

What Linux distro + version are you using? Will reproduce this today, thanks!

Seems that CMake 2.8.11 contains target_compile_definitions

https://cmake.org/cmake/help/v2.8.11/cmake.html#command:target_compile_definitions

and this is the earliest version that started to have the directive.

We should update the make file to reflect this

This is fixed
