# Fix compilation for CMake versions >= 3.1
#
# New Policy 0054:
# CMake 3.1 and above no longer implicitly dereference variables
# or interpret keywords in an if() command argument when it is a
# Quoted Argument.
# See http://www.cmake.org/cmake/help/v3.1/policy/CMP0054.html
#
# New Policy 0053:
# CMake 3.1 introduced faster implementation of evaluation of the
# Variable References and Escape Sequences. This breaks compilation
# here.
# See http://www.cmake.org/cmake/help/v3.1/policy/CMP0053.html
#
# Set those policies to be treated the legacy (CMake < 3.1) way.
