Command `if(a MATCHES ...)` has the same flaw:
`if(<variable|string> MATCHES regex)`:

set(MYSTRING "B")
set(A "MYSTRING")
if("${A}" MATCHES "^MYSTRING$")
# do *not* go here even A is MYSTRING (use *variable* MYSTRING)
endif()
This should work without dereferencing A, i.e.:
if(A MATCHES "^MYSTRING$")
# Bingo
endif()
Yes, but what if you need to combine some values, like: `if("${A}-${B}"
MATCHES ...)`?
Note that `if(A MATCHES "first-part" AND B MATCHES "second-part")` is
not the solutions in some cases, for example:
if("${A}${B}" MATCHES "/home/my/dir-A/")
should work for both A,B = {"/home/", "my/dir-A/"} and {"/home/my/",
"dir-A/"}
Also you always need keep in mind that it's not a string, but a regular
expression, example:
set(A "path/to/test/project")
set(B "path/to/test.project")
message("A and B same dir?")
if(A MATCHES "^${B}$")
message("surprise")
endif()
