Summary0008823: if(variable STREQUAL string) can treak LHS as a variable name
DescriptionConsider the following code snippet.

set(var "stuff")
set(stuff ON)
if(var STREQUAL "stuff")
  message("var STREQUAL stuff")
else()
  message("NOT var STREQUAL stuff")
endif()

According to the documentation, the LHS of STREQUAL should be treated as a string.

         if(variable STREQUAL string)
         if(string STREQUAL string)

However the behavior of the if statement changes depending on if 'stuff' is defined contrary to the documentation.

For comparison, MATCHES works as expected (results not dependent on the variable 'stuff' being defined).

 I made a slight error in the description: LHS should probably be RHS.
