[CMake] $<TARGET_FILE:tgt> in the add_custom_command()

[aaron.meadows at thomsonreuters.com]

Looks like '+' is not a valid character for the target name. 

 

Specifically, cmGeneratorExpression.cxx does not have it as part of the
regular expression to match target names: (line 23 on)

 

 

  this->TargetInfo.compile("^\\$<TARGET"

                           "(|_SONAME|_LINKER)"  // File with what
purpose?

                           "_FILE(|_NAME|_DIR):" // Filename component.

                           "([A-Za-z0-9_.-]+)"   // Target name.

                           ">$");

 

(In case you're unfamiliar with regular expressions, that + is just to
denote 1 or more of the things between the [ and ] . )

 

I tried adding + to that list, but I'm not sure how (if it's possible)
to escape it (and it resulted in a regular expression compile error
(runtime)).  I'd suggest using something else instead of a + in your
target name.

Hi,

 

If the project name has a symbols "-" or "+" the $<TARGET_FILE:tgt> in
the add_custom_command() return Error: "Error evaluating generator
expression"

 

For example:

SET ( PROJECT_NAME "00010-Liquid+Gas_as_capture " )

set ( SRCS_MAIN_CPT main.c      )

add_executable ( ${ PROJECT_NAME } ${SRCS_MAIN_CPT} )

 

add_custom_command ( TARGET ${ PROJECT_NAME } POST_BUILD 

                                            COMMAND "$<TARGET_FILE:${
PROJECT_NAME }>" 

                                            ARGS "$<TARGET_FILE_DIR:${
PROJECT_NAME }>/110.cnf"

                                            COMMENT "Running cpt.exe..."

 


)

 

When I run the CMake I received the following error:

 

"CMake Error at problems.rt.Cmake:114 (add_custom_command):

  Error evaluating generator expression:

    $<TARGET_FILE:00010-Liquid+Gas_as_capture>

Expression syntax not recognized."

 

Is this a bug or some syntax limitation?

 

Regards,

Alexey
