OpenCV build from source Windows make error "RC Object"

Question

I downloaded the latest source from github and configured opencv and the contrib modules. I can seem to build. I already turned off FFMPEG, which I manually downloaded the .dll previously, i know that has been a recent problem. I have succeeded in the past. But now i'm getting to

C:\mingw\bin\windres.exe: invalid option -- W
Usage: C:\mingw\bin\windres.exe [option(s)] [input-file] [output-file]
 The options are:
  -i --input=<file>            Name input file
  -o --output=<file>           Name output file
  -J --input-format=<format>   Specify input format
  -O --output-format=<format>  Specify output format
  -F --target=<target>         Specify COFF target
     --preprocessor=<program>  Program to use to preprocess rc file
     --preprocessor-arg=<arg>  Additional preprocessor argument
  -I --include-dir=<dir>       Include directory when preprocessing rc file
  -D --define <sym>[=<val>]    Define SYM when preprocessing rc file
  -U --undefine <sym>          Undefine SYM when preprocessing rc file
  -v --verbose                 Verbose - tells you what it's doing
  -c --codepage=<codepage>     Specify default codepage
  -l --language=<val>          Set language when reading rc file
     --use-temp-file           Use a temporary file instead of popen to read
                               the preprocessor output
     --no-use-temp-file        Use popen (default)

FORMAT is one of rc, res, or coff, and is deduced from the file name
extension if not specified.  A single file name is an input file.
No input-file is stdin, default rc.  No output-file is stdout, default rc.

Is there a cmake flag that gets around this? opencv_core sounds pretty crucial...

Answer 1

I think this might be it: https://github.com/opencv/opencv/issues/9100

The work around is at the bottom

Workaround is to turn off CMake option: ENABLE_PRECOMPILED_HEADERS=OFF
