What I do not follow is why there is an implicit evaluation of "TOTO"
into "B" (in both this case or the next I explicitely asked for a
string containing the content of the variable ${arg}, if I had
intended the content of the variable which name is in ${arg} I would
have written ${${arg}}.
If it is any consolence to you, this is one of the most-hated
(anti-)features
of cmake. The best you can do is to embrace this oddity (it's not going
to go
away soon), and use a different idiom:
Instead of ``"${var}" STREQUAL "VALUE"'', write:
IF ( var MATCHES "^VALUE$" )
NOOOOO, please don't! I try hard to kill all those as it requires
compiling a regular expression for a simple string match. Just change it
to something that is no valid variable name, i.e. will never get
expanded:
if (" ${arg}" STREQUAL " TOTO")
