My cmake was version 3.9.0 so I uninstalled it and installed 3.12.1. Rebooted and tried again. cmake threw the following warning but did compete.
CMake Warning (dev) at CMakeLists.txt:287 (FIND_PACKAGE):
Policy CMP0074 is not set: find_package uses <PackageName>_ROOT variables.
Run "cmake --help-policy CMP0074" for policy details. Use the cmake_policy
command to set the policy and suppress this warning.
CMake variable ZLIB_ROOT is set to:
C:/EQ/Source/dependencies/zlib_x86
For compatibility, CMake is ignoring the variable.
This warning is for project developers. Use -Wno-dev to suppress it.
Still failed compile with exact same errors. I deleted everything in the output directory and tried again. Same result.
