window env variable and cmake path

[craig.scott]

@alice

find_path(_opencv_INCLUDE_DIRS
	NAMES include/opencv_app.h
	PATHS "${LIB_ROOT}/opencv"
)

Arguments following NAMES cannot include a directory, they must be file names only.

@alice

I use three times PATHS
Can I only declare a variable to replace them?
I dont know what is the function?

I can’t follow what you’re asking. Can you please provide more detail so that your question(s) are clearer?
