Come escludo un singolo file da un cmake `file (GLOB ...)` pattern?

My CMakeLists.txtcontiene questa riga:

file(GLOB lib_srcs Half/half.cpp Iex/*.cpp IlmThread/*.cpp Imath/*.cpp IlmImf/*.cpp)

e la IlmImfcartella contiene b44ExpLogTable.cpp, che devo escludere dalla build.

Come ottenerlo?

È possibile utilizzare la listfunzione per manipolare l'elenco, ad esempio:

list(REMOVE_ITEM <list> <value> [<value> ...])

Nel tuo caso, forse qualcosa del genere funzionerà:

list(REMOVE_ITEM lib_srcs "IlmImf/b44ExpLogTable.cpp")

FILTER è un'altra opzione che potrebbe essere più conveniente in alcuni casi:

list(FILTER <list> <INCLUDE|EXCLUDE> REGEX <regular_expression>)

Questa riga esclude ogni elemento che termina con il nome file richiesto:

list(FILTER lib_srcs EXCLUDE REGEX ".*b44ExpLogTable.cpp$")

Ecco la specifica Regex per cmake:

The following characters have special meaning in regular expressions:

^         Matches at beginning of input
$         Matches at end of input
.         Matches any single character
[ ]       Matches any character(s) inside the brackets
[^ ]      Matches any character(s) not inside the brackets
 -        Inside brackets, specifies an inclusive range between
          characters on either side e.g. [a-f] is [abcdef]
          To match a literal - using brackets, make it the first
          or the last character e.g. [+*/-] matches basic
          mathematical operators.
*         Matches preceding pattern zero or more times
+         Matches preceding pattern one or more times
?         Matches preceding pattern zero or once only
|         Matches a pattern on either side of the |
()        Saves a matched subexpression, which can be referenced
          in the REGEX REPLACE operation. Additionally it is saved
          by all regular expression-related commands, including
          e.g. if( MATCHES ), in the variables CMAKE_MATCH_(0..9).
