[Tarantool-patches] [PATCH] cmake: set CMP0037 policy to NEW by default

[Olga Arkhangelskaia]

Hi Igor! Thanks for the review.

I did not get Sasha's approach. However, according to cmake 
documentations name test in

add_custom_target can be used if the modules CTest or CPAck is enabled.

https://cmake.org/cmake/help/latest/policy/CMP0037.html?highlight=cmp0037

So we just need to use NEW behaviour and cmake 3.11 and above.

See:

-if(POLICY CMP0037)
-    cmake_policy(SET CMP0037 OLD)
-endif(POLICY CMP0037)
-

+ if(POLICY CMP0037)
+    cmake_policy(SET CMP0037 NEW)
+ endif(POLICY CMP0037)
+
