Makefile parsing bug? #25469

The following lines in CNTK's Makefile appear to break syntax highlighting in VSCode. The first breaks all highlighting after it, and the nested ifdefs don't show up highlighted as "ifdef". I don't know enough about any of this to say whether this is a VSCode or CNTK problem, but thought I'd start here :)

Apologies for weird markdown due to code

1. Line 103

CXXVER_GE480:= $(shell expr `$(CXX) -dumpversion | sed -e 's/\.\([0-9][0-9]\)/\1/g' -e 's/\.\([0-9]\)/0\1/g' -e 's/^[0-9]\{3,4\}$$/&00/'` \>= 40800)

2. Line 122

ifdef CUDA_PATH
  ifndef GDK_INCLUDE_PATH
